What Is Lymphoma ?

[Extraced from EHealthMD]

Lymphoma is a cancer of the lymphatic system. The lymphatic system carries lymph fluid and white blood cells throughout body. The purpose of the lymphatic system is to fight infections.

Like all cancers, lymphoma happens when the body's cells grow out of control, often causing tumors to grow. Most lymphomas are made up of white blood cells called either T cells or B cells.

Lymphoma cells are sometimes found in the blood, but tend to form solid tumors in the lymph system or in organs. These tumors can often be felt as a painless lump or swollen gland almost anywhere in the body.

About the Lymphatic System
The lymphatic system helps to filter impurities, bacteria, and viruses from the body. The lymphatic system is made up of the lymph nodes [Small, bean-shaped organs located throughout the body along the vessels of the lymphatic system. The lymph nodes filter impurities from the body and store white blood cells that fight infection and other diseases. Clusters of lymph nodes are found in the underarms, groin, neck, chest, and abdomen. Also known as lymph glands], spleen [An organ that is part of the lymphatic system. The spleen produces lymphocytes, filters the blood, stores blood cells, and destroys those that are aging. It is located on the left side of the abdomen near the stomach], and special tubes that extend throughout the body like blood vessels.

Swollen glands are actually enlarged lymph nodes. Lymph nodes act as alert centers which activate the immune system to attack viruses, bacteria, or other foreign substances.



Hodgkin's Lymphoma
Hodgkin's lymphoma, also known as Hodgkin's disease, is a specific form of lymphoma. The cancer cells found in Hodgkin's disease have traits that differ from other lymphomas.

Unlike other forms of lymphoma, Hodgkin's disease usually spreads in a predictable way from one lymph node region to the next. Hodgkin's disease tends to respond differently to treatment than does non-Hodgkin's lymphoma.
Non-Hodgkin's Lymphoma

Non-Hodgkin's lymphoma includes many different cancers of the lymphatic system. Lymphomas are identified according to what type of cells they contain or where they occur in the body.



Most non-Hodgkin's lymphomas are found in the lymph nodes or lymphatic organs. Lymphatic tissues and cells are found throughout the body. So, lymphomas can also develop in the liver, stomach, nervous system or in other organs.

What Causes Lymphoma ?
The cause of most lymphomas is not known. Most are probably caused by mutations in certain genes, called oncogenes, which then allow normal cells to divide out of control.

These factors may increase a person's risk of getting lymphoma [A cancer of the lymphatic system] :

* Exposure to chemicals such as certain solvents, pesticides, herbicides, and water contaminated with nitrate.

* Taking drugs that suppress the immune system.

* Having an autoimmune disease [A disease in which the immune system attacks body's own tissues], such as lupus or rheumatoid arthritis.

* Having stomach ulcers or gastritis caused by a kind of bacteria called H. pyelori.

* Having a weakened immune system. For example, people with AIDS are 50 to100 times more likely to develop lymphoma than people who are not infected with the AIDS virus.

* Having one of the viruses that may increase risk for some types of lymphoma. For instance, in Africa, most Burkitt's lymphoma cells also carry the Epstein-Barr virus (EBV). In the United States, however, most Burkitt's lymphoma cells do not carry EBV. Viruses called HTLV-I appear to cause lymphoma in Japan, the Caribbean, and the southeastern United States. Another virus, called HHV-8, has been found in most cases of body cavity-based lymphomas (BCBL).

What Are The Symptoms ?
The first sign of lymphoma is often a painless lump or swollen gland in the neck, abdomen, underarm, or groin area. Lymphomas are often discovered during a visit to the doctor for another reason, or during a routine physical exam.

Other symptoms may include :

* Red patches on the skin.

* Nausea, vomiting, or abdominal pain.

* Coughing or breathlessness.

Some people with lymphoma develop other symptoms, called B symptoms [Symptoms that some people experience when they have lymphoma. B symptoms are non-specific In other words, they don't mean that lymphoma is present for sure, but it should be ruled out if the symptoms last longer than a couple of weeks. B symptoms include: drenching night sweats, unexplained weight loss (usually more than 10% of total body weight), fever of more than 100 degrees Fahrenheit, itching skin, and unusual tiredness], which include :

* Drenching night sweats.

* Unexplained weight loss, usually more than 10% of total body weight.

* Fever of more than 100 degrees Farenheit, which can come and go, especially in the evening.

* Itching skin, usually without a rash.

* Unusual tiredness.

Having these symptoms does not necessarily mean that a person has lymphoma, but if these symptoms last longer than two or three weeks, you should see a doctor.

What Are The Different Types Of Lymphoma ?
There are many different types of lymphoma. Researchers continue to seek better ways to group lymphomas so that doctors can predict the best treatment for a particular type of tumor.

In most cases the type of lymphoma is less important than the grade and stage of a particular lymphoma.

The different categories of lymphoma can seem very complicated, but they are based on :

* The appearance or histology of the cancer cells under a microscope.

* What kinds of genetic mutations they carry.

* Whether they form tight clusters (nodular) or are spread throughout a lymph [The almost colorless fluid that travels through the lymphatic system and carries cells that help fight infection and disease] node or other organ of the body (diffuse).

* What type of cell they arose from.

* What types of proteins the lymphoma cells have on their surface.

* Where they occur in the body.

Many types of lymphoma have traits that overlap with one another so it is often difficult to group them into definite categories. Also, many lymphomas that begin as one type gradually develop into another.

Some types of non-Hodgkin's lymphoma are distinct, either because of the age group they most often affect or the form they take. These include :

* Lymphoblastic lymphoma (LBL) - This form occurs more often in children than adults, and accounts for about 30% of all lymphomas in children. It is an aggressive, fast-growing form of lymphoma. In the past, it has been fatal for many patients. Today, intensive chemotherapy [Treatment with anti-cancer drugs] has greatly improved the chance of surviving LBL.

* Burkitt's lymphoma - This form of lymphoma has been found in Africa, where infection with Epstein-Barr virus may play a role in its cause. Burkitt's lymphoma is also seen in other parts of the world, but in most of these cases a virus doesn't seem to be involved. Burkitt's usually causes a large tumor either in the bone of the jaw, or in the abdomen [The center part of the body that contains the stomach, intestines, liver, gallbladder, and other organs].

* Diffuse histiocytic lymphoma (DHL) - Also called reticulosarcoma, this type of lymphoma is made of a substance that is more like connective tissue [The type of tissue that makes up the supporting structure of the lymph nodes and other organs, in the same way that beams and girders make up the supporting structure of a building] than white blood cells [The cells of the immune system that fight infection, attack foreign substances or cells, and sometimes kill cancer cells]. DHL is usually slow-growing, hard to treat, and often returns after treatment.

* Cutaneous T-cell lymphoma (CTLC) - Also called mycosis fungoides [another name for cutaneous T cell lymphoma (CTLC), which affects the skin] or Sezary syndrome, this kind of lymphoma affects the skin. In CTLC, white blood cells in the skin become cancerous and eventually cause tumors to form. This form tends to grow slowly over many years. In the early stages of CTLC, the skin may develop dry, scaly, red or dark patches and begin to itch. Eventually, raised tumors form on the skin. When the cancer becomes more advanced, it may spread to the blood, and from there to other organs.

In addition to the therapies used for other types of lymphoma, two additional treatments are used for CTLC. One is phototherapy [A treatment in which a drug that makes cancer cells sensitive to light is given to the patient, and a special light is then shone on the cancer cells to kill them], in which a drug that makes cancer cells sensitive to light is given to the patient, and a special light is then shone on the cancer cells to kill them. The other treatment is total skin electron-beam radiation therapy [A form of treatment that uses high-energy radiation from x-rays, neutrons, and other sources to kill cancer cells and shrink tumors] or TSEB, in which the entire surface of the skin is exposed to radiation.

Today, treating CTLC often causes the cancer to disappear, or go into remission [Disappearance of any sign of cancer cells and all symptoms of cancer. When this happens, the cancer is said to be in remission. A remission may be temporary or permanent], but it is a very difficult cancer to cure if not caught early. Treatment does help the symptoms, however, and can often increase a patient's life. New combinations of therapies are being studied in the hopes that more cases can be kept in remission for a longer time.

* Lymphoplasmacytoid lymphoma (LPL) with Waldenstrom's macroglobulinemia - LPL develops when special white blood cells called plasma cells [White blood cells called B cells that have been triggered into make antibodies] begin to divide out of control, becoming cancerous. It is a slow-growing or indolent form of lymphoma.

LPL cells also release too much of a kind of antibody [Antibodies are proteins that help white blood cells fight off viruses and bacteria, by binding to foreign invaders and signaling the immune cells to attack] called IgM into the blood. This condition is called Waldenstrom's macroglobulinemia. In addition to the cancer, this is dangerous because it causes a thickening of the blood. This in turn can cause fatigue, headaches, weight loss, visual problems, confusion, dizziness, loss of coordination and excessive bleeding. If not treated, the thickened blood can tax the heart so much that it leads to heart failure.

How Is Lymphoma Diagnosed ?

Lymphoma is diagnosed through :

* Physical exam

* Blood tests

* Imaging tests

* Biopsy

Physical Exam
If a person has symptoms of lymphoma or notices a lump or swelling, the doctor will perform a complete physical exam. This includes checking the lymph nodes [Small, bean-shaped organs located throughout the body along the vessels of the lymphatic system. The lymph nodes filter impurities from the body and store white blood cells that fight infection and other diseases. Clusters of lymph nodes are found in the underarms, groin, neck, chest, and abdomen. Also known as lymph glands] in the neck, armpit, or groin [The area in the body where the thigh meets the abdomen], and checking for an enlarged liver or spleen [An organ that is part of the lymphatic system. The spleen produces lymphocytes, filters the blood, stores blood cells, and destroys those that are aging. It is located on the left side of the abdomen near the stomach]. The doctor will ask about recent illnesses or infections, and overall health.

Blood Tests
Blood tests may rule out infections and other types of disease. The blood will also be checked to see if cancer [A disease in which any of the body's cells begin to divide out of control, causing a tumor to form or too many of these cells to spread throughout the body] cells or cancer-related enzymes are present. Other factors in the blood, such as anemia [Too few red blood cells. Anemia can cause tiredness, shortness of breath, and make it harder for the body to fight infection. may be looked at]. These tests may also provide information on how far the cancer has spread.
Imaging Tests

The doctor will probably order imaging tests that can view inside the body, such as :

* X-rays.

* CT (computed tomography) scan.

* MRI [Magnetic resonance imaging. A procedure in which a magnet linked to a computer is used to create detailed pictures of areas inside the body] (magnetic resonance imaging) scan.

* Lymphangiogram [X-ray of the lymphatic system. A dye is injected into a lymphatic vessel and travels throughout the lymphatic system. The dye makes them visible on the x-ray], a test using a special dye that makes the lymph nodes and vessels show up on an x-ray.

Biopsy
A biopsy tells whether a lump or swollen gland is truly a lymphoma. To do a biopsy, the doctor will surgically remove a small sample of tissue, and a pathologist A doctor who identifies diseases by studying cells and tissues under a microscope. looks at it under a microscope. Cancer cells look a certain way under the microscope, which allows the pathologist to identify them.

Need To Know :

Ruling Out Other Conditions
Infections like the flu, mononucleosis (mono), or strep throat can also cause swollen lymph nodes, so these symptoms should not automatically cause concern of cancer. If the swelling does not go down after a couple of weeks, you should see a doctor.

Swollen lymph nodes due to infection are usually fairly soft and somewhat tender or painful, while cancerous nodes are usually firm, rubbery and painless.

Certain chemicals or medications, such as antibiotics and drugs for epilepsy, can cause swollen lymph nodes and other symptoms that may resemble symptoms for lymphoma. To avoid this confusion, tell your doctor what medications you have been taking recently.

There are other serious conditions that can cause swollen lymph nodes. These include AIDS, other types of cancer, and disorders of the lymph [The almost colorless fluid that travels through the lymphatic system and carries cells that help fight infection and disease] system that are not cancer. The tests described above will help to rule out these conditions.

What Are Grading And Staging ?
When a doctor has found cancer cells and is sure that they are from a lymphoma, it is important to know the grade and the stage of the cancer. Lymphomas of different grades and stages grow at different rates, and respond differently to treatment.

* The grade of a lymphoma refers to how quickly, or aggressively, it is growing.

* The stage of lymphoma or any cancer depends on how far it has spread throughout the body.

* Grade and stage are the most important factors for predicting how a patient will do and for deciding on the best treatment.

Grade
For non-Hodgkin's lymphoma, grade is the most important factor in predicting the likely outcome with and without treatment. Lymphomas are usually divided into three main grade categories :

* Low-grade or indolent : slow-growing lymphomas that can go for many years without treatment.

* Intermediate-grade or aggressive : faster-growing lymphomas.

* High-grade or highly aggressive : very fast-growing lymphomas.

Stage
In order to decide on the best treatment, it is helpful to know what stage the cancer has reached. The stage describes how far it has spread through the body from where it began. Lymphomas are grouped into four stages, from Stage I to Stage IV. Stage IV is the most serious.

The stage and whether the cancer has spread or remains as a single tumor [An abnormal mass of tissue that occurs when cells divide out of control. Tumors may be either benign (not cancerous) or malignant (cancerous). Benign tumors do not spread throughout the body and when they are removed they do not grow back. Malignant, or cancerous, tumors may do both] is more important for slow-growing, low-grade lymphomas than for the more aggressive high-grade tumors.

To find out what stage a lymphoma has reached, the doctor will want to find out :

* How many lymph nodes [Small, bean-shaped organs located throughout the body along the vessels of the lymphatic system. The lymph nodes filter impurities from the body and store white blood cells that fight infection and other diseases. Clusters of lymph nodes are found in the underarms, groin, neck, chest, and abdomen. Also known as lymph glands] contain cancer cells and where are they located.

* Whether these lymph nodes are above, below, or on both sides of the diaphragm [The thin muscle below the lungs and heart that separates the chest from the abdomen]

* Whether the disease spread to the bone marrow [The soft, spongy tissue in the center of large bones that produces white blood cells, red blood cells, and platelets] the spleen [An organ that is part of the lymphatic system. The spleen produces lymphocytes, filters the blood, stores blood cells, and destroys those that are aging. It is located on the left side of the abdomen near the stomach], or to other organs outside the lymphatic system [The tissues and organs that produce, store, and carry white blood cells that fight infection and other diseases. This system includes the bone marrow, spleen, thymus, and lymph nodes and a network of vessels that carry lymph and white blood cells into all the tissues of the body].

To find out the stage of a lymphoma, a doctor will usually do several new tests and repeat ones that were done to diagnose the lymphoma. These may include:

* A bone marrow biopsy [The removal of cells or tissues for examination under a microscope] to show whether the cancer has spread into the bone marrow. To do a bone marrow biopsy, a doctor removes a sample of bone marrow through a needle inserted into the hip or another large bone.

* A CT scan [Computed tomography scan. A series of detailed pictures inside the body; the pictures are created by a computer linked to a special x-ray machine. Also called a CAT scan] or lymphangiogram [X-ray of the lymphatic system. A dye is injected into a lymphatic vessel and travels throughout the lymphatic system. The dye makes them visible on the x-ray].

* Taking samples from other tissues, such as the liver or stomach, to see whether tumor cells are present.

* Sometimes, a doctor may want to do an operation called a laparotomy to look for additional tumors. During a laparotomy, a surgeon takes samples of tissue from inside the abdomen [The center part of the body that contains the stomach, intestines, liver, gallbladder, and other organs. . If a CT scan can be done, a laparotomy is usually not necessary. Results from a CT scan are usually considered more accurate].

* Depending on where cancer cells or tumors are found, other tissue samples and tests may need to be done.

The four stages of lymphoma are :

* Stage I : A single tumor which hasn't spread.

* Stage II : More than one tumor, but the tumors are all found in lymph nodes on the same side of the diaphragm (all above or all below). Stage II can also mean that a tumor has spread to another organ, but that it is close to the original lymph [The almost colorless fluid that travels through the lymphatic system and carries cells that help fight infection and disease] node tumor.

* Stage III : More than one tumor with the tumors found on different sides (above and below) of the diaphragm. There may be tumors in the spleen or more than one tumor in nearby organs.

* Stage IV : Many tumors spread throughout an organ such as the liver or stomach, as well as in the lymph nodes. Stage [A measure of how far a cancer has spread throughout the body. Stages range from Stage I, which is a localized tumor that has not spread, to Stage IV, in which the cancer has spread to parts of the body far away from the original tumor. Stage I cancers have a better outlook than do Stage IV cancers] IV can also refer to a single tumor in another organ, plus tumors in distant lymph nodes.

What Treatments Are Available For Lymphoma ?
The methods of treatment used for lymphoma include :

* Chemotherapy (drugs) and radiation therapy
* Bone marrow transplant
* Biologic therapy

The combination of drugs and therapies used will depend on the type of lymphoma.

Chemotherapy And Radiation Therapy
Chemotherapy is the use of drugs to kill cancer [A disease in which any of the body's cells begin to divide out of control, causing a tumor to form or too many of these cells to spread throughout the body] cells. Chemotherapy for non-Hodgkin's lymphoma usually includes a combination of several drugs.

Radiation therapy uses high-energy x-rays to kill cancer cells and shrink tumors.

Chemotherapy and radiation therapy are the most common treatments for non-Hodgkin's lymphoma. Because of the risk that a lymphoma has spread beyond the original tumor [An abnormal mass of tissue that occurs when cells divide out of control. Tumors may be either benign (not cancerous) or malignant (cancerous). Benign tumors do not spread throughout the body and when they are removed they do not grow back. Malignant, or cancerous, tumors may do both], surgery alone isn't usually enough.

Chemotherapy is called a systemic treatment because the drugs travel throughout the body. This means that even those cancer cells that have not yet been found may be killed. Patients may receive chemotherapy alone or in combination with radiation therapy.

Bone Marrow Transplant
One form of chemotherapy, called high-dose chemotherapy (HDCT), uses very high doses of toxic drugs to kill all possible tumor cells. Because these high doses also kill most of the bone marrow, patients are then given a bone marrow transplant to restore their ability to make new red and white blood cells [The cells of the immune system that fight infection, attack foreign substances or cells, and sometimes kill cancer cells]

Bone marrow may be taken from the patient before chemotherapy begins and given back to the patient after treatment is done. Or, bone marrow from another person may be used.

Biological Therapy
We now understand a great deal about cancer and the body's defense systems. Biological theraphy [Uses chemicals or proteins made by the body's own cells to activate the body's defenses against a cancer. Also called immunotherapy or biological response modifier (BRM) therapy], also called biological response modifier therapy (BRMT), uses chemicals made by the body's own cells in order to activate the body's defenses against cancer.

Many biological therapies are still experimental, but research is being done to develop and improve them. Scientists and doctors hope that they will soon be able to treat most forms of cancer using these therapies, combined with treatments like chemotherapy and radiation therapy.

The different approaches to biological therapy include :

* Immunotherapy
* Angiogenesis inhibitors
* Gene therapy

Immunotherapy
In one kind of immunotherapy [A form of biological therapy that stimulates the immune system to fight and kill cancer cells. Some forms include cytokine therapy, monoclonal antibodies, and tumor vaccines] chemicals called cytokines [chemicals produced by the immune system that stimulate white blood cells to attack and kill viruses, bacteria, foreign cells, or cancer cells] are used to activate white blood cells. Sometimes, when the immune system is activated in this way, it will fight and kill tumor cells. Two cytokines being used are called interferon and interleukin.

Antibodies are proteins that help white blood cells fight off viruses and bacteria. Antibodies bind to foreign invaders and signal the immune cells to attack. Monoclonal antibodies Antibodies are proteins that help white blood cells fight off viruses and bacteria, by binding to foreign invaders and signaling the immune cells to attack. Monoclonal antibodies are antibodies that are made in the laboratory to bind to only one single type of molecule. They are currently being used to bind to tumor cells, either to signal to immune cells to attack, or to carry toxic agents directly to the tumor. are antibodies that are made in the laboratory to bind to only one single type of molecule.

Many cancer cells carry proteins called tumor antigens on their surface. Because cancer cells are usually the only ones to carry these proteins, tumor antigens make good targets. Researchers hope that monoclonal antibodies against these tumor antigens will bind to them and signal the immune system to attack the tumor cells.

Two approaches are being studied for treating cancer with monoclonal antibodies. In one, the antibodies signal the body's own immune cells to attack and kill the tumor cells. In the other, powerful anti-cancer drugs are linked to monoclonal antibodies which then carry the drugs straight to the tumor. This means that the drug is aimed directly at the cancer cells rather than at healthy tissues.

The U.S. Food and Drug Administration (FDA) has approved Rituxan, a monoclonal antibody [Antibodies are proteins that help white blood cells fight off viruses and bacteria, by binding to foreign invaders and signaling the immune cells to attack] for treating lymphoma, and are considering approval of a similar drug, Bexxar. Rather than binding to proteins found only on cancer cells, these two antibodies bind an antigen found on almost all B-lymphocytes. This causes both cancerous and healthy, mature B-lymphocytes to be killed. But because the youngest B cells [White blood cells that make antibodies. Some forms of lymphoma are made of B cells] in the body do not have the antigen, they are not affected by the treatment, and can grow and mature to replace those that were killed during treatment.

Another new immunotherapy is the use of tumor vaccines. In much the same way that a polio vaccine activates your immune system to fight off the virus if you are ever infected, tumor vaccines use a person's own tumor cells to activate the immune system to destroy the tumor.

Angiogenesis Inhibitors
Angiogenesis inhibitors [Chemicals produced by the body which stop the growth of new blood vessels. Because cancerous tumors must have a supply of new blood vessels in order to keep growing, angiogenesis inhibitors are being tested as a treatment for lymphoma and other cancers] are chemicals that block the formation of new blood vessels. Tumors need to create a whole new blood supply in order to keep growing, so they cause new blood vessels to be formed. In mice, angiogenesis inhibitors have blocked the growth of many types of cancer. This highly experimental form of treatment has been successful in mice. Clinical trials are underway to test the treatment in people.

Gene Therapy
In gene therapy [Treating a disease by putting good copies of a gene into cells. For cancer, this might include putting genes into the cancer cells that will make them stop growing out of control, or it might mean putting genes into the cancer cells that will make them self-destruct] pieces of DNA [The molecule that is used to build the genetic code in every cell. Genes are made of DNA] are placed into cells to correct something that has gone wrong with those cells, or to make the cells self-destruct. Because most cancers are now known to result from damage to genes that keep cells from growing out of control, gene therapy of cancer cells may someday be able to correct the problem or force cancer cells to destroy themselves. Gene therapy for cancer is still highly experimental.

How Can I Help Treatment Go Smoothly ?
Because many non-Hodgkin's lymphomas now have a good chance of being cured, anyone diagnosed with lymphoma should be referred to an oncologist as soon as possible. One reason for this is because treatments are constantly being improved and an oncologist is most likely to be aware of new and better therapies.

The oncologist and the family doctor can then work as a team to arrange the best possible treatment and follow-up care. The medical team may also include a hematologist and/or a radiation oncologist.

You can help to make your treatment go as smoothly as possible by :

* Giving your doctor the most complete medical history that you can.

* Telling your doctor about any side effects [Problems that occur due to treatment. Common side effects of cancer treatment are fatigue, nausea, vomiting, decreased blood cell counts, hair loss, and mouth sores] or problems you have during treatment.

* Trying to eat right.

* Taking care of yourself, including getting pain relief when you need to.

* Following your doctor's recommendations, including follow-up and long-term care.

What To Tell Your Doctor ?
Before and during treatment for any form of cancer, your doctor will need to know about any medications you may be taking. This includes over-the-counter medicines for allergies, indigestion, colds, and pain relief and any vitamin, mineral or herbal supplements you may take. Remember to tell your doctor about prescription medication from other doctors.

If You Have Side Effects During Treatment
If you develop any symptoms that seem unusual or if there is anything you are unsure about, don't hesitate to call your doctor. Call your doctor if you notice any of the following :

* Losing or gaining 10 pounds or more.
* Nosebleeds.
* Severe itching or rash on skin.
* Wheezing or any other trouble breathing.
* Feeling very tired.
* Constipation.
* Sores in your mouth or throat.
* Coughing a lot.
* Feeling tingling in your fingers and toes.
* Ringing in your ears.
* Red dots under your skin.
* Black and blue marks.
* Nausea or vomiting.
* Diarrhea.
* A fever of 101 degrees or higher.
* Chills, especially shaking chills.
* Redness, swelling, or tenderness, especially around a wound or sore.
* Hair loss.
* Headaches or changes in vision.
* Warm to hot feeling of an arm or leg.
* Unusual bleeding, for instance from your gums or nose.
* Unusual bruising.

Try To Eat Right
Although it is sometimes hard to eat a balanced diet during cancer therapy, it will help your body recover much sooner from the effects of the treatment and the cancer. Every day, try to eat and drink :

* At least 5 servings of fruits and vegetables.

* Protein-rich foods like chicken, fish, cheese or eggs.

* Carbohydrates, found in breads, pastas, rice and grains. Whole grains like whole-wheat bread and pasta, and brown rice are more nutritious than processed foods like white bread, pastries, and sugary foods and will help your body recover sooner.

* Plenty of liquids.

* Soups can combine all of these and may be easy to eat.

If it is hard to eat, try soft, soothing foods like milkshakes and soft sandwiches. Acidic or spicy foods or foods that are too hot or too cold can make eating more uncomfortable. Eating small meals more often can help you to meet your nutritional needs.

Taking Care Of Yourself
Cancer therapies can make the mouth sore and prone to infection. Try to brush your teeth with a soft toothbrush after every meal. If your mouth is too sore to brush, try to at least rinse with water.

Try to get plenty of rest. This will allow your body to heal and help fight infections. Avoiding people who have colds, flu, or other infections may decrease your risk of being infected.

Dealing with cancer and cancer therapy can be extremely stressful. You may find yourself becoming depressed, or you may find yourself discovering new wisdom.

Try to find emotional support and someone you can talk to about your feelings. This could be your family, someone in your church, a counselor, or a support group for cancer patients. For more information, go to Additional Sources of Information.
Getting Adequate Pain Relief

Cancer can be very painful. While cancer pain cannot always be completely stopped, you do have the right to have relief from pain.

Some people are afraid that if they take powerful painkillers they will become addicted. Some doctors and other caregivers also still hold this belief.

Studies have shown that people who take pain medications in the right way, for real pain, rarely become addicted. Being able to keep pain under control actually makes people less likely to become addicted. Other studies have shown that severe, prolonged pain is actually harmful to your body and its ability to heal. Even if you have to take pain medication for a long time, this does not mean you have become addicted.

In addition to pain-relieving drugs, techniques such as relaxation therapy, hypnosis, visualization, and massage can also help ease pain. Discuss these with your medical team.

Be sure to discuss pain relief with your doctor if and when you need it. Try to work with your medical team and play an active role in your own care. Simply feeling in control of your situation can often do a lot to help ease pain.

If you feel that your medical team is not allowing you the medication or other treatment that you truly need for your pain, you may want to discuss the problem with a counselor or seek a second opinion from another doctor.
Follow-Up Care

Because lymphomas can recur To occur again, to come back. Even when lymphoma appears cured, it may recur. even if it seems that they have been cured, it is important to have checkups every few months even after you have finished your treatments. Treatments for lymphoma can be toxic and there is always some chance that they will cause medical problems in the future. Staying in touch with your family physician and reporting anything that concerns you in between follow-up visits may improve your long-term outcome.

Lymphoma Treatment In Children
If your child has been diagnosed with lymphoma, call your child's doctor whenever you have questions. If you are unsure whether something should be reported, discuss it with your child's doctor.

According to the National Cancer Institute, you should let your physician or another medical team member know if your child has any of the following :

* A fever or other sign of infection, or just doesn't look well.

* Exposure to a contagious infection, especially chickenpox or measles (unless your child is known to be immune from prior exposure).

* Persistent headaches, pain, or discomfort anywhere in the body.

* Difficulty in walking or bending.

* Pain during urination or bowel movements.

* Reddened or swollen areas.

* Vomiting, unless you have been told that your child might vomit after chemotherapy Treatment with anti-cancer drugs. or radiation.

* Problems with eyesight such as blurred or double vision.

* Bleeding. In addition to obvious bleeding such as nosebleeds, signs of bleeding can be seen in the stools (red or black), in the urine (pink, red, or brown), in vomit (red or brown, like coffee grounds), or the presence of multiple bruises.

* Other troublesome side effects of treatment such as mouth sores, constipation (beyond 2 days), diarrhea, and easy bruising.

* Marked depression or a sudden change in behavior.

Remember to check with your child's physician when your child is due to receive any kind of vaccination or any dental care.

What Is The Outlook ?
By choosing the best treatment, your doctors will try to bring the cancer into remission, so that no more cancer can be found and there are no more symptoms.

The outlook for lymphoma and other cancers is measured in survival rates, or how many patients have been able to live for two years, five years, ten years, etc. before or after treatment.

Because there are so many different types of lymphoma and because the outlook for each patient varies widely, it is very difficult to predict the outcome for an individual case. We do know some general facts:

* Although high-grade, aggressive lymphomas are usually quite deadly without treatment, many can now be cured with proper treatment.

* On the other hand, most low-grade, indolent lymphomas can be left alone for years. But, they usually prove to be very stubborn and surprisingly difficult to cure. They often return, usually within a couple of years after treatment. Repeating the treatment can then often put them back into remission, but they usually come back.

* A lymphoma with a lower stage A measure of how far a cancer has spread throughout the body. Stages range from Stage I, which is a localized tumor that has not spread, to Stage IV, in which the cancer has spread to parts of the body far away from the original tumor. Stage I cancers have a better outlook than do Stage IV cancers. (Stage I or II) has a better outlook than one with a higher stage (Stage III or IV).

Certain factors make the chance of remission and long-term survival more likely. These positive factors include :

* Small, localized tumors.

* Absence of B symptoms Symptoms that some people experience when they have lymphoma. B symptoms are non-specific In other words, they don't mean that lymphoma is present for sure, but it should be ruled out if the symptoms last longer than a couple of weeks. B symptoms include: drenching night sweats, unexplained weight loss (usually more than 10% of total body weight), fever of more than 100 degrees F., itching skin, and unusual tiredness. .

* Young age

* Female gender

Q : What are some of the possible side effects Problems that occur due to treatment. Common side effects of cancer treatment are fatigue, nausea, vomiting, decreased blood cell counts, hair loss, and mouth sores. of treatment?

A : The effects of chemotherapy [Treatment with anti-cancer drugs] and radiation therapy [A form of treatment that uses high-energy radiation from x-rays, neutrons, and other sources to kill cancer cells and shrink tumors] can be harsh. Remember that they are mostly temporary and won't last forever. Talk with your doctor about what to expect and which symptoms to report if you experience them. Side effects may include :

* Fatigue.

* Nausea and vomiting.

* Pain.

* Hair loss.

* Anemia [Too few red blood cells. Anemia can cause tiredness, shortness of breath, and make it harder for the body to fight infection]

* Central nervous system problems.

* Infection.

* Blood clotting problems or excessive bleeding.

* Mouth, gum, and throat problems.

* Diarrhea.

* Constipation.

* Nerve and muscle effects, like tingling, burning, weakness, or pain in muscles or skin.

* Effects on skin and nails, such as redness, rashes, itching, peeling, dryness, acne or increased sensitivity to the sun.

* Radiation recall, when the skin turns red and may blister.

* Kidney and bladder effects.

* Flu-like symptoms.

* Fluid retention.

* Temporary or permanent problems having children.

Your doctor can give you information on drugs and other ways to reduce side effects.

Q : What other types of problems is lymphoma likely to cause ?

A : Even before treatment begins, lymphoma may cause anemia. Anemia can cause extreme fatigue. Lymphoma may also interfere with the immune system, making infections more likely. Sleep disorders, depression and anxiety are also common effects. In the advanced stages of cancer [A disease in which any of the body's cells begin to divide out of control, causing a tumor to form or too many of these cells to spread throughout the body], people often develop cachexia, in which they stop eating and develop profound fatigue and weakness. Speak with your doctor if you are having trouble with any of these symptoms. Anemia can be treated, and sleep disorders can often be helped with medications. Medications are also available to help with cachexia.

Q: Are there other things besides drugs that can ease pain or the side effects of treatment?

A: There are a number of complementary approaches that have helped many people deal with the discomfort and pain of lymphoma and treatments for cancer. These include:

* Relaxation techniques.

* Biofeedback, a technique for learning how to change your response to stress.

* Massage.

* Visualization and guided imagery.

* Hypnosis.

* Transcutaneous Electric Nerve Stimulation (TENS), a therapy using electric stimulation of nerves and muscles to relieve pain.

* Acupuncture or acupressure (acupuncture is not recommended for people receiving chemotherapy, as it may increase bleeding).

* Skin stimulation (heat, cold, pressure).

Support groups for lymphoma patients offer more information on learning about these techniques.

Q : Can lymphomas occur in other parts of the body than the lymph nodes Small, bean-shaped organs located throughout the body along the vessels of the lymphatic system. The lymph nodes filter impurities from the body and store white blood cells that fight infection and other diseases. Clusters of lymph nodes are found in the underarms, groin, neck, chest, and abdomen. Also known as lymph glands. ?

A : Yes, tumors can be found in other organs, such as the liver, the stomach, or even the brain. Sometimes tumors in organs are found even if tumors have not been found in the lymph nodes.

Q : Are there alternative medicines (herbs, shark cartilage, etc.) that will work for lymphoma?

A : So far, no herbal or other alternative therapy has been proven to help lymphoma. For this reason, and because lymphoma can be a life-threatening disease, the safest course is to have medical treatments prescribed and tracked by your medical team. If you decide to try alternative therapies such as herbs or homeopathy in addition to the medical treatments advised by your medical team, be sure to discuss all treatments with your doctor first. Some alternative therapies may interfere with your treatment, lowering their chance of success. Others may become toxic when taken with chemotherapy drugs. The National Cancer Institute (NCI) offers information on alternative therapies that have been used to treat cancer. This information describes the results of scientific studies on these therapies. The National Institute of Health (NIH) has also set up the National Center for Complementary and Alternative Medicine [Treatments that have not traditionally been used in standard Western medicine, and are not widely taught in medical schools. These may include naturopathic medicine (herbs and plants), homeopathy, traditional Chinese medicine, Ayurvedic medicine, and others] (NCCAM), which is conducting scientific studies on herbal and other alternative medicines.

Q : Are new treatments for lymphoma being developed ?

A : Yes. Many new therapies, or combinations of therapies, are being studied. Working with a trained oncologist A doctor who specializes in diagnosing and treating cancer. will help to insure that you receive the most up-to-date and effective treatment.

Q : Would a clinical trial A research study that tests the effectiveness of new treatments in people. be right for me? How can I find out about clinical trials for new treatments for lymphoma ?

A : You may want to consider enrolling in a clinical research trial. This is a study in which some patients are given the standard treatment for a particular type of cancer, while other patients are given a new treatment. Any treatment tested in people must first pass rigorous tests in animals. The National Cancer Institute (See Additional Sources of Information.) has an up-to-date list of ongoing clinical trials of new therapies for cancer.

Swine (Pig) Influenza and You



A swine flu outbreak that appears to have caused fatalities in humans in Mexico and nonfatal cases in the United States prompted the World Health Organization (WHO) this weekend to urge countries around the world to be alert for suspicious cases of influenza.

WHO Chief Margaret Chan says the global body is taking the outbreak very seriously, though comparisons with the 1918 epidemic are premature.

Here are some facts about swine flu :

What is swine flu ?

Swine flu is a highly contagious acute respiratory disease normally found in pigs. It spreads through tiny particles in the air or by direct contact. According to WHO it tends to infect large numbers of a given pig population, killing between 1 and 4 percent of those affected. Not every animal infected displays symptoms.

Where do outbreaks occur ?

Swine flu is considered endemic in the United States, and outbreaks in pigs have also been reported elsewhere in North America, South America, Europe, Africa, and parts of eastern Asia.

What are the signs and symptoms of swine flu in people ?

The symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. In the past, severe illness (pneumonia and respiratory failure) and deaths have been reported with swine flu infection in people. Like seasonal flu, swine flu may cause a worsening of underlying chronic medical conditions.

How high is the risk of a pandemic ?

Since the swine flu outbreaks in Mexico and U.S. Were identified, the risk of a pandemic has increased. Health officials worry the swine flu might develop into a form easily spread among humans. To do this, it could combine with a human flu virus or mutate on its own into a transmissible form. Experts worry that the more the virus circulates, the more likely a pandemic strain will emerge. But there is no way to predict when a pandemic strain will develop.

How do you catch swine flu ?

Spread of swine flu can occur in two ways :

· Through contact with infected pigs or environments contaminated with swine flu viruses.

· Through contact with a person with swine flu. Human-to-human spread of swine flu has been documented also and is thought to occur in the same way as seasonal flu. Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.

Are there medicines to treat swine flu ?

Yes. The use of oseltamivir or zanamivir has been recommended for the treatment and/or prevention of infection with these swine influenza viruses. Antiviral drugs are prescription medicines (pills, liquid or an inhaler) that fight against the flu by keeping flu viruses from reproducing in your body. If you get sick, antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious flu complications. For treatment, antiviral drugs work best if started soon after getting sick (within 2 days of symptoms).

How long can an infected person spread swine flu to others ?

People with swine influenza virus infection should be considered potentially contagious as long as they are symptomatic and possible for up to 7 days following illness onset. Children, especially younger children, might potentially be contagious for longer periods.

What can I do to protect myself from getting sick ?

There is no vaccine available right now to protect against swine flu. There are everyday actions that can help prevent the spread of germs that cause respiratory illnesses like influenza. Take these everyday steps to protect your health:

· Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.

· Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective.

· Try to avoid close contact with sick people.

· If you get sick with influenza, it is recommended that you stay home from work or school and limit contact with others to keep from infecting them. Avoid touching your eyes, nose or mouth. Germs spread this way.

What should I do if I get sick ?

If you are sick, you should contact your Health Care Centre for consultation. Stay home and avoid contact with other people as much as possible to keep from spreading your illness to others.

If you become ill and experience any of the following warning signs, seek emergency medical care.

In children emergency warning signs that need urgent medical attention include:

· Fast breathing or trouble breathing

· Bluish skin color

· Not drinking enough fluids

· Not waking up or not interacting

· Being so irritable that the child does not want to be held

· Flu-like symptoms improve but then return with fever and worse cough

· Fever with a rash

In adults, emergency warning signs that need urgent medical attention include :

· Difficulty breathing or shortness of breath

· Pain or pressure in the chest or abdomen

· Sudden dizziness

· Confusion

· Severe or persistent vomiting

Can I get swine influenza from eating or preparing pork ?

No. Swine influenza viruses are not spread by food. You cannot get swine influenza from eating pork or pork products. Eating properly handled and cooked pork products is safe.

Health Benefits of Asparagus !


Three types of asparagus on a shop display, with white asparagus at the back and green asparagus in the middle. The plant at the front is Ornithogalum pyrenaicum, is commonly called wild asparagus.

******************************************

Several years ago, I had a man seeking asparagus for a friend who had cancer. He gave me a photocopied copy of an article,entitled, `Asparagus for cancer' printed in Cancer News Journal, December 1979.

I will share it here, just as it was shared with me: 'I am a biochemist, and have specialized in the relation of diet to health for over 5 years'. Several years ago, I learned of the discovery of Richard R.Vensal, D.D.S. that asparagus might cure cancer. Since then, I have worked with him on his project. We have accumulated a number of favourable case histories.

Here are a few examples:

Case No. 1

A man with an almost hopeless case of Hodgkin's disease (cancer of the lymph glands) who was completely incapacitated. Within 1 year of starting the asparagus therapy, his doctors were unable to detect any signs of cancer, and he was back on a schedule of strenuous exercise.

Case No. 2

A successful businessman 68 years old who suffered from cancer of the bladder for 16 years. After years of medical treatments, including radiation without improvement, he went on asparagus. Within 3 months, examinations revealed that his bladder tumor had disappeared and that his kidneys were normal.

Case No. 3

A man who had lung cancer. On March 5th 1971, he was put on the operating table where they found lung cancer so widely spread that it was inoperable. The surgeon sewed him up and declared his case hopeless. On April 5th he heard about the asparagus therapy and immediately started taking it. By August, x-ray pictures revealed that all signs of the cancer had disappeared. He is back at his regular business routine.

Case No. 4

A woman who was troubled for a number of years with skin cancer. She finally developed different skin cancers which were diagnosed by asking specialist as advanced. Within 3 months after starting on asparagus, her skin specialist said that her skin looked fine and no more skin lesions. This woman reported that the asparagus therapy also cured her kidney disease, which started in 1949. She had over 10 operations for kidney stones, and was receiving government disability payments for an inoperable, terminal, kidney condition. She attributes the cure of this kidney trouble entirely to the asparagus.

I was not surprised at this result, as 'The elements of Material Medica', edited in 1854 by a Professor at the University of Pennsylvania, stated that asparagus was used as a popular remedy for kidney stones. He even referred to experiments, in 1739, on the power of asparagus in dissolving stones.

We would have other case histories but the medical establishment has interfered with our obtaining some of the records. I am therefore appealing to readers to spread this good 20news and help us to gather a large number of case histories that will overwhelm the medical skeptics about this unbelievably simple and natural remedy. For the treatment, asparagus should be cooked before using, and therefore canned asparagus is just as good as fresh.

I have corresponded with the two leading canners of asparagus, Giant Giant and Stokely, and I am satisfied that these brands contain no pesticides or preservatives.

PROCEDURE :

1) Place the cooked asparagus in a blender and liquefy to make a puree, and store in the refrigerator.

2) Give the patient 4 full tablespoons twice daily, morning and evening.

Patients usually show some improvement in from 2-4 weeks. It can be diluted with water and used as a cold or hot drink. This suggested dosage is based on present experience, but certainly larger amounts can do no harm and may be needed in some cases.

As a biochemist I am convinced of the old saying that 'what cures can prevent'. Based on this theory, my wife and I have been using asparagus puree as a beverage with our meals. We take 02 tablespoons diluted in water to suit our taste wit breakfast and with dinner. I take mine hot and my wife prefers hers cold.

For years we have made it a practice to have blood surveys taken as part of our regular checkups.

The last blood survey, taken by a medical doctor who specializes in the nutritional approach to health, showed substantial improvements in all categories over the last one, and we can attribute these improvements to nothing but the asparagus drink..

As a biochemist, I have made an extensive study of all aspects of cancer, and all of the proposed cures. As a result, I am convinced that asparagus fits in better with the latest theorie about cancer. Asparagus contains a good supply of protein called histones, which are believed to be active in controlling cell growth. For that reason, I believe asparagus can be said to contain a substance that I call cell growth normalizer. That accounts for its action on cancer and inacting as a general body tonic. In any event, regardless of theory, asparagus used as we suggest, is a harmless substance.

The FDA cannot prevent you from using it and it may do you much good.. It has been reported by the US National Cancer Institute, that asparagus is the highest tested food containing glutathione, which is considered one of the body ' s most potent anticarcinogens and antioxidants.

What are Nasal Polyps ?



[Extracted from Wisegeek.com & patient.co.uk]

Nasal polyps are noncancerous growths which spontaneously form in nasal passages for largely unknown reasons. There may be a connection between the formation of nasal polyps and allergic rhinitis, but a runny nose alone does not always trigger nasal polyps. Some medical experts suggest a link between sinus infections and the increased likelihood of polyp formation, but others suggest that the majority of nasal polyps form idiopathically, meaning there is no definitive cause.

Symptoms of nasal polyps include blocked nasal airways, sudden onset of snoring, reduction in senses of smell or taste, and discolored nasal mucus. The polyps themselves may appear as enlarged sacs of mucus with a jelly-like consistency. Unlike benign or malignant polyps which may form in other areas of the body, nasal polyps are not usually attached to the skin and are not usually viewed as evidence of a more serious medical condition.

There are several different courses of treatment for nasal polyps, most of which involve the application of anti-inflammatory drugs such as steroids. Nasal sprays containing steroids generally shrink the nasal polyps themselves while antibiotics may address any secondary infections. Significant amounts of discolored nasal mucus is often a sign of infected nasal polyps residing out of sight in the upper nasal passages. A medical professional can use a special instrument to examine nasal passages for the development of nasal polyps.

On rare occasions, nasal polyps may become problematic enough to require surgical intervention. Complete blockage of nasal airways by enlarged nasal polyps, for example, could require an aspiration procedure, meaning the polyps would be carefully drained by a surgeon and the patient would be given antibiotics to counteract post-procedural infection. Self-treatment of nasal polyps is strongly discouraged, since the punctured sacs of infected mucus may not heal properly, or possibly cause scar tissue to form in the nasal passages.

What are nasal polyps ?

Nasal polyps are soft fleshy swellings that grow inside the nose. They may be yellowish, grey or pink in colour. They are common and are not cancerous (that is, they are benign). Nasal polyps can vary greatly in size. There may be only one but sometimes several grow like a 'small bunch of grapes' on a stem.

What causes nasal polyps ?

In most cases the cause is not known. It is thought that ongoing (chronic) inflammation in the nose causes overgrowth of the lining of the nostril. This can sometimes lead to small polyps forming. These may then gradually grow larger. Polyps usually affect both nostrils. The cause of the inflammation is unclear in most cases. However, certain conditions make nose inflammation and polyps more likely. These include: asthma, allergy to aspirin, cystic fibrosis, and some rare conditions of the nose.

Who gets nasal polyps ?

About 1 in 100 people will develop nasal polyps at some stage in their life. Nasal polyps can affect anyone. However, most cases occur in people over the age of 40 years. They are four times more common in men than in women. Nasal polyps are uncommon in children. A child with nasal polyps should also be checked for cystic fibrosis as cystic fibrosis is a 'risk factor' for developing nasal polyps.



What are the symptoms of nasal polyps ?

* The main symptom is a blocked feeling in the nose. You may find it difficult to breathe through your nose. You may then have to breathe through your mouth for much of the time. This is especially troublesome at night and your sleep may be affected.

* Watering from the nose (rhinorrhoea) is common.

* A 'post nasal drip' may occur. This is the sensation of something continually running down the back of your throat due to mucus coming from the back of large polyps.

* Your sense of smell and taste may be dulled or lost.

* A blocked nose may make your voice sound different.

* Larger polyps may cause headaches and snoring.

* Very large untreated polyps can make your nose and front of your face enlarge.

* Sometimes polyps block the drainage channel of the sinuses. This can make you more prone to sinusitis (infection of the sinuses).

* Large polyps sometimes interfere with breathing at night and cause obstructive sleep apnoea. (See separate leaflet called 'Sleep Apnoea'.)

Do I need any tests ?

An ear nose and throat specialist can usually diagnose nasal polyps from their appearance. Sometimes a CT scan of the front of your face is ordered. This may be done to find out how large the polyps are, or if they are also in your sinuses. A small flexible telescope may also be used to look inside your nose and assess the extent of the polyps.

Benefits in eating Cabbages



Cabbage Benefits

Cabbage has long been noted for its ability to help people lose weight. From the cabbage soup diet to eating cabbage in other recipes, cabbage can help people lose weight and keep the weight off. What you may not realize, however is that Cabbage is full of many vitamins and minerals. It has been a staple food throughout many parts of the world and is a beneficial addition to any person’s diet.

Cabbage is a member of the Cruciferae or Brassicaceae family of vegetables. These are commonly referred to as crucifers or the cabbage family. Cabbage is related to the wild mustard plant and is low in carbohydrates. Cabbage may be eaten raw as served in coleslaw, or it may be cooked and used for soups, stews, and borscht. In Germany, cabbage is pickle in vinegar and served as Sauerkraut. Also, throughout history cabbage has been harvested for its medicinal purposes. It is high in amino acids and is believed to help those who are suffering from any type of inflammation.



In addition to being low in carbohydrates, cabbage is also an excellent source of Vitamin C. In fact, one serving or cup of cabbage provides more than 50% of the daily requirement for Vitamin C. It is also an excellent source of Vitamin K. One cup of cabbage provides more than 90% of the recommended daily allowance. Vitamin K plays an important role in helping the body fight against invaders and bacteria. Since cabbage is high in Vitamin K, it helps to strengthen the Immune system and help the body fight against sickness and disease.



Cabbage is also a rich source of dietary fiber, providing nearly 15% of the daily recommended requirement. Fiber is very important for ensuring that the body’s digestive system is functioning and regular. Eating cabbage is a great way to ensure that your digestive track is functioning at optimum level.

In addition to being high in Vitamin K, Vitamin C, and dietary fiber cabbage also has many other nutrients that makes it a great food source. It contains Manganese, Vitamin B6, Folate, Omega 3 Fatty Acids, Vitamin B1 and Vitamin B2, Calcium, Potassium, Vitamin A, Tryptophan, Protein, and Magnesium.



It may be the amount of calories that has helped make cabbage a great food choice for those who are dieting or watching their weight. One serving (one cup) of cabbage contains a mere 33 calories. This is why those who are on the cabbage soup diet can eat endless amounts of the soup without gaining weight, while still feeling healthy. There are many diets that promote a sense of well being, but cabbage is an excellent choice of many nutrients and minerals making it a great choice for those watching their weight. However, it is important to realize that cabbage is low in both carbohydrates as well as protein. It is a vegetable and therefore its nutritious sustenance is compromised mostly of vitamins and minerals. Yet when cabbage is added to a healthy diet, its nutritional content is abundant.

What is Tennis Elbow ?



[Extracted from WiseGeek.com]

Tennis elbow, or lateral epicondylitis, is a painful condition that affects the outside or lateral side of the elbow and can cause pain even when gripping or carrying a very light object like a coffee cup. About half of all tennis players will experience tennis elbow at some point in their lives, yet tennis players only account for about 5% of all those who suffer from tennis elbow, as the condition can be brought on by many activities.

Tennis elbow is often confused with two other painful conditions: golfer's elbow or medial epicondylitis, and bursitis. Golfer's elbow is brought about by the same types of activities as tennis elbow, but the pain is primarily felt on the inside of the elbow rather than the outside, while the pain of bursitis is at the back of the elbow.

Tennis elbow will typically cause recurring pain at the outside top of the forearm just below the elbow, and pain may radiate down the arm. Bending the arm, lifting or straightening the arm will also cause pain due to inflamed muscles and tendons. Typical bouts of tennis elbow last 6-12 weeks, but it can also last shorter or longer periods of time.

Tennis elbow is caused by small tears in the tendons and muscles. Tendons anchor muscles to bone. When tendons tear it takes much longer to heal than muscle tissue because tendons receive less blood and oxygen than muscles.

Once tendons and muscles are injured, the site is always vulnerable to re-tearing. Further injury can lead to hemorrhaging and calcium deposits in the tissues. A protein called collagen can also create inflammation that can press on the radial nerve that controls muscles in the arm and hand.

Because tennis elbow is associated with injury to the tendon it is often referred to as tendonitis, however, if the bone itself feels sore and muscles are involved it is epicondylitis or tennis elbow. Although tennis elbow involves inflammation of the tissues at the injury site, it does not cause swelling of the arm, which could be indicative of arthritis, gout or even infection.

The recommended treatment for tennis elbow is to stop whatever activities have caused it and allow the arm to rest until all pain has ceased. At that point massage and exercise may be of value to strengthen the arm against further injury. Slow gentle stretching of the arm for 10-15 minutes before engaging in any activity is also recommended.

For special cases of tennis elbow your doctor may suggest anti-inflammatory creams, injections or even surgery. However surgery is a last resort suggested to less than 3% of those who suffer from tennis elbow. In this case tears in the tendon may be repaired or the tendon may be cut free of the bone to release the stress, though this is rarely chosen as it leaves the tendon useless.



Tennis Elbow (lateral epicondylitis)
Outside of Elbow - Cause & Symptoms

The onset of pain, on the outside (lateral) of the elbow, is usually gradual with tenderness felt on or below the joint's bony prominence. Movements such as gripping, lifting and carrying tend to be troublesome.



Golfer’s Elbow (medial epicondylitis)
Inside of Elbow - Cause & Symptoms

The causes of golfers elbow are similar to tennis elbow but pain and tenderness are felt on the inside (medial) of the elbow, on or around the joint's bony prominence.



Bursitis
Back of Elbow - Cause & Symptoms

Often due to excessive leaning on the joint or a direct blow or fall onto the tip of the elbow. A lump can often be seen and the elbow is painful at the back of the joint.

To prevent tennis elbow from recurring, experts suggest modifying the activity that caused it, stretching or warming up the arm, exercising the arm to build muscle strength, and resting the arm between activities.

If you are experiencing persistent pain in your elbow or arm it is always best to see your doctor in order to have the problem professionally diagnosed and treated

What is meant by a Ruptured Spleen ?


[Extracted from MayoClinic.Com]

A ruptured spleen is a serious condition that can occur when your spleen experiences a trauma. Without emergency treatment, a ruptured spleen can cause life-threatening bleeding.

Your spleen is located just under your rib cage on your left side, a prime spot for injury. With enough force, a blow to your abdomen — during a sporting mishap, a fist fight or a car accident, for example — might lead to a ruptured spleen.

In the past, ruptured spleens usually were removed in emergency surgery. These days, however, it's common for people with ruptured spleens to be treated instead with several days of hospital care to help the spleen heal.

The spleen helps your body fight infection and filter unwanted material, such as old or damaged blood cells. The spleen also produces red blood cells and certain types of white blood cells. A ruptured spleen may pour a large amount of blood into your abdominal cavity.

Abdominal pain and tenderness are the classic symptoms of a ruptured spleen. If internal bleeding causes your blood pressure to drop, you may become lightheaded or confused. Blurred vision and fainting are possible as well.



When to see a doctor ?

A ruptured spleen is a medical emergency. If you have pain in the left upper abdomen or signs and symptoms of low blood pressure — such as lightheadedness, confusion, blurred vision or fainting — following an injury, seek emergency medical care.
A ruptured spleen is typically caused by a blow to the left upper abdomen or the left lower chest. Sporting mishaps, fist fights and car accidents are common triggers. An injured spleen may rupture soon after the abdominal trauma or, in some cases, days or even weeks after the injury.

An enlarged spleen — which may be caused by various underlying problems, from mononucleosis and other infections to liver disease and blood cancers — may sometimes rupture with trauma to the abdomen. In fact, a ruptured spleen is the most significant complication of mononucleosis.

A ruptured spleen can cause life-threatening bleeding into your abdominal cavity.

In a critical situation, a physical exam may be the only diagnostic test before emergency surgery. In other cases, a sample of fluid from your abdomen may be tested for the presence of blood. If time allows, your doctor may use CT scans or other imaging tests to identify or rule out other possible causes of your symptoms.

Many small and many moderate-sized injuries to the spleen can heal without surgery. You're likely to stay in the hospital for up to a week while doctors observe your condition and provide nonsurgical care, such as blood transfusions, if necessary. If your injury is severe, your spleen may need to be surgically repaired or, in some cases, removed. Surgery to remove your spleen is called splenectomy.

Many splenectomies are done with a small incision and a slender tube equipped with a camera lens and light (laparoscope), but emergency surgery may require an open procedure. If you've lost a large amount of blood, you may need transfusions to improve your circulation.

Life without a spleen

You can live an active life without a spleen, but you're more likely to contract serious or even life-threatening infections. If your spleen is removed, your doctor may recommend a pneumonia vaccine, as well as yearly flu vaccines. In some cases, preventive antibiotics may be recommended as well — especially if you have any other conditions that increase your risk of serious infections.

After a splenectomy, notify your doctor at the first sign of an infection. Make sure anyone caring for you knows that you've had your spleen removed.

What is a Herniated Disc ?



[Extracted from ABOUT.COM]

Many patients with back pain, leg pain, or weakness of the lower extremity muscles are diagnosed with a herniated disc. When a disc herniation occurs, the cushion that sits between the spinal vertebra is pushed outside its normal position. A herniated disc would not be a problem if it weren't for the spinal nerves that are very close to the edge of these spinal discs.

What is the spinal disc ?

The spinal disc is a soft cushion that sits between each vertabrae of the spine. This spinal disc becomes more rigid with age. In a young individual, the disc is soft and elastic, but like so many other structures in the body, the disc gradually looses its elasticity and is more vulnerable to injury. In fact, even in individuals as young as 30, MRIs show evidence of disc deterioration in about 30% of people.

What happens with a 'herniated disc' ?

As the spinal disc becomes less elastic, it can rupture. When the disc ruptures, a portion of the spinal disc pushes outside its normal boundary--this is called a herniated disc. When a herniated disc bulges out from between the vertebrae, the spinal nerves and spinal cord can become pinched. There is normally a little extra space around the spinal cord and spinal nerves, but if enough of the herniated disc is pushed out of place, then these structures may be compressed.



What causes symptoms of a herniated disc ?

When the herniated disc ruptures and pushes out, the nerves may become pinched. A herniated disc may occur suddenly in an event such as a fall or an accident, or may occur gradually with repetitive straining of the spine. Often people who experience a herniated disc already have spinal stenosis, a problem that causes narrowing of the space around the spinal cord and spinal nerves. When a herniated disc occurs, the space for the nerves is further diminished, and irritation of the nerve results.

What are the symptoms of a herniated disc ?

When the spinal cord or spinal nerves become compressed, they don't work properly. This means that abnormal signals may get passed from the compressed nerves, or signals may not get passed at all. Common symptoms of a herniated disc include :


a) Electric Shock Pain
Pressure on the nerve can cause abnormal sensations, commonly experienced as electric shock pains. When the compression occurs in the cervical (neck) region, the shocks go down your arms, when the compression is in the lumbar (low back) region, the shocks go down your legs.

b) Tingling & Numbness
Patients often have abnormal sensations such as tingling, numbness, or pins and needles. These symptoms may be experienced in the same region as painful electric shock sensations.

c) Muscle Weakness
Because of the nerve irritation, signals from the brain may be interrupted causing muscle weakness. Nerve irritation can also be tested by examining reflexes.

d) Bowel or Bladder Problems
These symptoms are important because it may be a sign of cauda equina syndrome, a possible condition resulting from a herniated disc. This is a medical emergency, and your should see your doctor immediately if you have problems urinating, having bowel movements, or if you have numbness around your genitals.

All of these symptoms are due to the irritation of the nerve from the herniated disc. By interfering with the pathway by which signals are sent from your brain out to your extremities and back to the brain, all of these symptoms can be caused by a herniated disc pressing against the nerves.

How is the diagnosis of a herniated disc made ?

Most often, your physician can make the diagnosis of a herniated disc by physical examination. By testing sensation, muscle strength, and reflexes, your physician can often establish the diagnosis of a herniated disc.

An MRI is commonly used to aid in making the diagnosis of a herniated disc. It is very important that patients understand that the MRI is only useful when used in conjunction with examination findings. It is normal for a MRI of the lumbar spine to have abnormalities, especially as people age. Patients in their 20s may begin to have signs of disc wear, and this type of wear would be expected on MRIs of patients in their 40s and 50s. This is the reason that your physician may not be concerned with some MRI findings noted by the radiologist.

Making the diagnosis of a herniated disc, and coming up with a treatment plan depends on the symptoms experienced by the patient, the physical examination findings, and the x-ray and MRI results. Only once this information is put together can a reasonable treatment plan be considered.

Treatment of a herniated disc depends on a number of factors including :

* Symptoms experienced by the patient
* Age of the patient
* Activity level of the patient
* Presence of worsening symptoms

Most often, treatments of a herniated disc begin conservatively, and become more aggressive if the symptoms persist. After diagnosing a herniated disc, treatment usually begins with :

1) Rest & Activity Modification
The first treatment is to rest and avoid activities that aggravate your symptoms. Many disc herniations will resolve is given time. In these cases, it is important to avoid activities that aggravate your symptoms.

2) Ice & Heat Applications
Ice and heat application can be extremely helpful in relieving the painful symptoms of a disc herniation. By helping to relax the muscles of the back, ice and heat applications can relieve muscle spasm and provide significant pain relief.

3) Physical Therapy
Physical therapy and lumbar stabilization exercises do not directly affect the herniated disc, but they can stabilize the lumbar spine muscles. This has an effect of decreasing the load experienced by the disc and vertebrae. Stronger, well balanced muscles help control the lumbar spine and minimize the risk or injury to the nerves and the disc.

4) Anti-Inflammatory Medications
Nonsteroidal anti-inflammatory medications (NSAIDs) are commonly prescribed, and often help relieve the pain associated with a disc herniation. By reducing inflammation, these medications can relieve some pressure on the compressed nerves. NSAIDs should be used under your doctor's supervision.

5) Oral Steroid Medications
Oral steroid medications can be very helpful in episodes of an acute (sudden) disc herniation. Medications used include Prednisone and Medrol. Like NSAIDs, these powerful anti-inflammatory medications reduce inflammation around the compressed nerves, thereby relieving symptoms.

6) Other Medications
Other medications often used include narcotic pain medications and muscle relaxers. Narcotic pain medications are useful for severe, short-term pain management. Unfortunately, these medication can make you drowsy and can be addictive. It is important to use these for only brief periods of time. Muscle relaxers are used to treat spasm of spinal muscles often seen with disc herniations. Often the muscle spasm is worse than the pain from the disc pressing on the nerves.

7) Epidural Steroid Injections
Injections of cortisone can be administered directly in the area of nerve compression. Like oral anti-inflammatory medications, the idea is to relieve the compression on the nerves. When the injection is used, the medication is delivered to the area of the disc herniation, rather than being taken orally and travelling throughout your body.

Is surgery necessary in the treatment of a disc herniation ?
As mentioned, treatment of a disc herniation usually begins with the steps listed above. However, surgical treatment of a herniated disc may be recommended soon after the injury if there is a significant neurological deficit to your problem. Symptoms on pain and sensory abnormalities usually do not require immediate intervention, but patients who have significant weakness, any evidence of cauda equina syndrome, or a rapidly progressing problem may require more prompt surgical treatment.

Most often surgery is recommended if more conservative measures do not relieve your symptoms. Surgery is performed to remove the herniated disc, and free up space around the compressed nerve. Depending on the size and location of the herniated disc, and associated problems (such as spinal stenosis, arthritis, etc.), the surgery can be done by several techniques. In very straightforward cases, endoscopic or microscopic excision of the herniated disc may be possible. However, this is not always recommended, and in some cases, a more significant surgery may need to be performed.

Lumbar Discectomy

A discectomy is a surgery done to remove a herniated disc from the spinal canal. When a disc herniation occurs, a fragment of the normal spinal disc is dislodged. This fragment may press against the spinal cord or the nerves that surround the spinal cord. This pressure causes the symptoms that are characteristic of herniated discs.

The surgical treatment of a herniated disc is to remove the fragment of spinal disc that is causing the pressure on the nerve. This procedure is called a discectomy. The traditional surgery is called an open discectomy. An open discectomy is a procedure where the surgeon uses a small incision and looks at the actual herniated disc in order to remove the disc and relieve the pressure on the nerve.

How is a discectomy performed ?

A discectomy is performed under general anesthesia. The procedure takes about an hour, depending on the extent of the disc herniation, the size of the patient, and other factors. A discectomy is done with the patient lying face down, and the back pointing upwards.

In order to remove the fragment of herniated disc, your surgeon will make an incision over the center of your back. The incision is usually about 3 centimeters in length. Your surgeon then carefully dissects the muscles away from the bone of your spine. Using special instruments, your surgeon removes a small amount of bone and ligament from the back of the spine. This part of the procedure is called a laminotomy.

Once this bone and ligament is removed, your surgeon can see, and protect, the spinal nerves. Once the disc herniation is found, the herniated disc fragment is removed. Depending on the appearance and the condition of the remaining disc, more disc fragments may be removed in hopes of avoiding another fragment of disc from herniating in the future. Once the disc has been cleaned out from the area around the nerves, the incision is closed and a bandage is applied.

What is the recovery from a discectomy ?

Patients often awaken from surgery with complete resolution of their leg pain; however, it is not unusual for these symptoms to take several weeks to slowly dissipate. Pain around the incision is common, but usually well controlled with oral pain medications. Patients often spend one night in the hospital, but are usually then discharged the following day. A lumbar corset brace may help with some symptoms of pain, but is not necessary in all cases.

Gentle activities are encouraged after surgery, such as sitting upright and walking. Patients must avoid lifting heavy objects, and should try not to bend or twist the back excessively. Patients should avoid strenuous activity or exercise until cleared by their doctor.

What are the potential complications of a discectomy ?

The most common problem of a discectomy is that there is a chance that another fragment of disc will herniate and cause similar symptoms down the road. This is a so-called recurrent disc herniation, and the risk of this occurring is about 10-15%.

Most patients find relief of much, if not all, of their symptoms from a discectomy. However, the success of the procedure is about 85-90%, meaning that 10% of patients who undergo a discectomy will still have persistent symptoms. Patients who have symptoms for long periods of time, or severe neurologic deficits (such as significant weakness) are at higher risk of incomplete recovery.

Other risks of surgery include spinal fluid leaks, bleeding, and infection. All of these can usually be treated, but may require a longer hospitalization or additional surgery.

What is endoscopic microdiscectomy ?

Newer techniques may allow your surgeon to perform a procedure called an endoscopic discectomy. In an endoscopic discectomy your surgeon uses special instruments and a camera to remove the herniated disc through very small incisions.

The endoscopic microdiscectomy is a procedure that accomplishes the same goal as a traditional open discectomy, removing the herniated disc, but uses a smaller incision. Instead of actually looking at the herniated disc fragment and removing it, your surgeon uses a small camera to find the fragment and special instruments to remove it. The procedure may not require general anesthesia, and is done through a smaller incision with less tissue dissection. Your surgeon uses x-ray and the camera to "see" where the disc herniation is, and special instruments to remove the fragment.

Endoscopic microdiscectomy is appropriate in some specific situations, but not in all. Many patients are better served with a traditional open discectomy. While the idea of a faster recovery is nice, it is more important that the surgery is properly performed. Therefore, if open discectomy is more appropriate in your situation, then the endoscopic procedure should not be done. Discuss with your doctor if endoscopic microdiscectomy may be appropriate for you.

Capsicum and Health Benefits !



Capsicum helps in curing many diseases that include lowering blood pressure, reducing cholesterol and warding off strokes and heart attacks, speeding up metabolism, treating colds and fevers, preventing cancer and pain control. Capsaicin is a flavorless, odorless chemical concentrated in the veins of chiles and peppers.

Capsicum contains Vitamins A and C, and beta-carotene. It's low in fat, calories and cholesterol. If you thought your diabetic diet was supposed to be boring, try spicing up your cuisine with capsaicin-based products, like hot sauce or jalapeno peppers.



Listed below are some of the health benefits of Capsicum :

* Enhances Metabolism: Capsicum increases the metabolism by lowering triglycerides, which are stored fats in blood corpuscles.This helps in burning calories.

* Anti Oxidant Property: Capsicum is an important source of vitamin A and vitamin C. These two vitamins are powerful antioxidants that help in fighting free radicals in the body and help in treating heart diseases, osteoarthritis, bronchial asthma, cataract etc. The free radicals are responsible for causing cellular damage, damage to nerves and blood vessels.

* Pain Relief: Scientists believe that the compound capsaicin found in capsicum blocks the transmission of pain from the skin to the spinal cord. This is considered helpful in treating neuralgia, pain associated with herpes zoster and postoperative amputation trauma.

* Cancer Prevention: The compound capsaicin is also believed to treat cancer by preventing carcinogens from binding with DNA. As a regular dietary intake, it has been found through various studies that eating capsicum can provide some protection from cancer.

* Prevents Clotting of Blood: Studies suggest that capsicum has the capacity to prevent clotting of blood. Vitamin C is found to play a major role in dissolving blood clots.

* Fights Food-Borne Bacterial Diseases: In a study it has been found that capsaicin content in capsicum is effective in fighting off food-borne bacterial diseases like Vibrio vulnificus bacteria found in raw shellfish.



Capsicum is a vegetable that comes in an exciting range of colors, like green, red and yellow. It is native to America and in fact, has been cultivated by the people of the tropical Americas since thousands of years. Known by a number of names, like chili pepper, bell pepper and red or green pepper, the vegetable is used as a spice, medicine and obviously, a vegetable. Apart from being great in taste, capsicum also holds a great degree of nutritional value and accords numerous health benefits to people.

What is Balut ?



Balut is an egg that has been fertilized and contains a partially developed embryo. In countries where the balut is considered to be a delicacy, a duck egg or a chicken egg may be used to prepare the dish. The mode of preparation for balut is very simple. Generally, the egg is boiled and eaten directly from the shell, in much the same manner that boiled and unfertilized eggs are eaten around the world.

In countries where balut is commonly served, the fertilized duck egg or chicken egg is considered to be a superior source of protein. The boiled embryo is also considered to add flavor and texture to the egg. A balut may be enjoyed as a quick snack along with beer or some form of ale, or be employed as the centerpiece for a meal.

Along with the basic method of boiling the fertilized chicken egg or duck egg, it is not uncommon for the exposed contents of the shell to be doused with vinegar, chili peppers, or a variety of spices. Some prefer to not eat the white sections remaining in the shell, while others consume all the contents found within the egg proper. Balut can also be included as a center for baked pastries, as well as mixed into an egg batter and fried into an entrée.

Balut is developed by allowing the fertilized egg to begin developing the embryo for several days. During this period, the egg is kept warm. Generally, eight or nine days of consistent warmth are sufficient to allow the embryo to develop. At this juncture, the balut is ready for boiling. After boiling the balut, the contents of the egg can be used in a number of different recipes. Generally, the balut is always served while still warm.

---------------------------------------------------------------------



Fertilized duck eggs sold as balut in the U.S. range from 16 to 20 days in age. The older the egg, the larger the chick and the more pronounced its feathers, bones, and beak. An embryo at 17 days has beak and feathers which are more developed at 20 days. Normally, after being fertilized, a chick hatches after 26 to 28 days of incubation.

The taste of the egg also depends on the breed of the laying duck. Different breeds of ducks supposedly produce balut varying in taste, with Muscovy ducks being hailed by some as the "cream of the crop". The kind of balut sold in the U.S. is made from duck eggs. Chicken eggs may be made into balut as well, but duck eggs are preferred by the majority of Filipino Americans since they are larger and thought to be better in taste.



But whether the fertilized egg is chicken or duck, there are two types of balut. One is called mamatong by Filipinos. Mamatong balut has the embryo floating on top of the white and yolk and the consumer can easily detect it. Roughly translated to mean "the float," mamatong occurs between 14 to 16 days. The second is balut sa puti where the embryo is wrapped by a thin, whitish membrane and one cannot tell whether there is an embryo or not. In balut sa puti, the embryo is hidden by the albumen's white film. Balut sa puti is 17 to 18 days old and it is the preferred favorite of Filipinos in the U.S. and in the Philippines. A folk belief in the Philippines lets people know if an egg has developed into mamatong or balut sa puti. One takes a balut egg and drops it in water. If it floats, it is mamatong, but if it sinks, it is balut sa puti.

Just how good and fresh a balut is after it has been boiled can be determined by its broth, called "soup" by balut eaters. After cracking a hole in the wide part of the shell, the consumer usually sips the broth before he or she eats any part of the tiny chick and remaining yolk. If the balut is good, its soup has a sweet, clean taste. Fresh balut can be good for ten days to two weeks. Cooked balut if stored in the refrigerator will last for as long as a month. But the longer the balut is in the refrigerator, the more likely that its liquid will be dried out.

What is Heavy Metal Poisoning ?

[Extracted from The Free Dictionary by Farlex]

Definition
Heavy metal poisoning is the toxic accumulation of heavy metals in the soft tissues of the body.

Description
Heavy metals are chemical elements that have a specific gravity (a measure of density) at least five times that of water. The heavy metals most often implicated in accidental human poisoning are lead, mercury, arsenic, and cadmium. More recently, thallium has gained some attention in the media as the poison used in several murder cases in the 1990s. Some heavy metals, such as zinc, copper, chromium, iron, and manganese, are required by the body in small amounts, but these same elements can be toxic in larger quantities.

Heavy metals may enter the body in food, water, or air, or by absorption through the skin. Once in the body, they compete with and displace essential minerals such as zinc, copper, magnesium, and calcium, and interfere with organ system function. People may come in contact with heavy metals in industrial work, pharmaceutical manufacturing, and agriculture. Children may be poisoned as a result of playing in contaminated soil. Lead poisoning in adults has been traced to the use of lead-based glazes on pottery vessels intended for use with food, and contamination of Ayurvedic and other imported herbal remedies. Arsenic and thallium have been mixed with food or beverages to attempt suicide or poison others.

Another form of mercury poisoning that is seen more and more frequently in the United States is self-injected mercury under the skin. Some boxers inject themselves with mercury in the belief that it adds muscle bulk. Metallic mercury is also used in folk medicine or religious rituals in various cultures. These practices increase the risk of mercury poisoning of children in these ethnic groups or subcultures.

Causes and symptoms
Symptoms will vary, depending on the nature and the quantity of the heavy metal ingested. Patients may complain of nausea, vomiting, diarrhea, stomach pain, headache, sweating, and a metallic taste in the mouth. Depending on the metal, there may be blue-black lines in the gum tissues. In severe cases, patients exhibit obvious impairment of cognitive, motor, and language skills. The expression "mad as a hatter" comes from the mercury poisoning prevalent in 17th-century France among hatmakers who soaked animal hides in a solution of mercuric nitrate to soften the hair.

Diagnosis
Heavy metal poisoning may be detected using blood and urine tests, hair and tissue analysis, or x ray. The diagnosis is often overlooked, however, because many of the early symptoms of heavy metal poisoning are nonspecific. The doctor should take a thorough patient history with particular emphasis on the patient's occupation.
In childhood, blood lead levels above 80 ug/dL generally indicate lead poisoning, however, significantly lower levels (>30 ug/dL) can cause mental retardation and other cognitive and behavioral problems in affected children. The Centers for Disease Control and Prevention considers a blood lead level of 10 ug/dL or higher in children a cause for concern. In adults, symptoms of lead poisoning are usually seen when blood lead levels exceed 80 ug/dL for a number of weeks.

Blood levels of mercury should not exceed 3.6 ug/dL, while urine levels should not exceed 15 ug/dL. Symptoms of mercury poisoning may be seen when mercury levels exceed 20 ug/dL in blood and 60 ug/dL in urine. Mercury levels in hair may be used to gauge the severity of chronic mercury exposure.

Since arsenic is rapidly cleared from the blood, blood arsenic levels may not be very useful in diagnosis. Arsenic in the urine (measured in a 24-hour collection following 48 hours without eating seafood) may exceed 50 ug/dL in people with arsenic poisoning. If acute arsenic or thallium poisoning is suspected, an x ray may reveal these substances in the abdomen (since both metals are opaque to x rays). Arsenic may also be detected in the hair and nails for months following exposure.
Cadmium toxicity is generally indicated when urine levels exceed 10 ug/dL of creatinine and blood levels exceed 5 ug/dL.

Thallium poisoning often causes hair loss (alopecia), numbness, and a burning sensation in the skin as well as nausea, vomiting, and dizziness. As little as 15-20 mg of thallium per kilogram of body weight is fatal in humans; however, smaller amounts can cause severe damage to the nervous system.

Treatment
When heavy metal poisoning is suspected, it is important to begin treatment as soon as possible to minimize long-term damage to the patient's nervous system and digestive tract. Heavy metal poisoning is considered a medical emergency, and the patient should be taken to a hospital emergency room.

The treatment for most heavy metal poisoning is chelation therapy. A chelating agent specific to the metal involved is given either orally, intramuscularly, or intravenously. The three most common chelating agents are calcium disodium edetate, dimercaprol (BAL), and penicillamine. The chelating agent encircles and binds to the metal in the body's tissues, forming a complex; that complex is then released from the tissue to travel in the bloodstream. The complex is filtered out of the blood by the kidneys and excreted in the urine. This process may be lengthy and painful, and typically requires hospitalization. Chelation therapy is effective in treating lead, mercury, and arsenic poisoning, but is not useful in treating cadmium poisoning. To date, no treatment has been proven effective for cadmium poisoning. Thallium poisoning is treated with a combination of Prussian blue (potassium ferric hexacyanoferrate) and a diuretic, because about 35% of it is excreted in the urine; however, if treatment is not started within 72 hours of ingesting the poisoning, damage to the patient's nervous system may be permanent.

In cases of acute mercury, arsenic, or thallium ingestion, vomiting may be induced. Activated charcoal may be given in cases of thallium poisoning. Washing out the stomach (gastric lavage) may also be useful. The patient may also require treatment such as intravenous fluids for such complications of poisoning as shock, anemia, and kidney failure.

Patients who have taken arsenic, thallium, or mercury in a suicide attempt will be seen by a psychiatrist as part of emergency treatment.

Prognosis
The chelation process can only halt further effects of the poisoning; it cannot reverse neurological damage already sustained.

Prevention
Because arsenic and thallium were commonly used in rat and insect poisons at one time, many countries have tried to lower the rate of accidental poisonings by banning the use of heavy metals in pest control products. Thallium was banned in the United States as a rodent poison in 1984. As a result, almost all recent cases of arsenic and thallium poisoning in the United States were deliberate rather than accidental.

Because exposure to heavy metals is often an occupational hazard, protective clothing and respirators should be provided and worn on the job. Protective clothing should then be left at the work site and not worn home, where it could carry toxic dust to family members. Industries are urged to reduce or replace the heavy metals in their processes wherever possible. Exposure to environmental sources of lead, including lead-based paints, plumbing fixtures, vehicle exhaust, and contaminated soil, should be reduced or eliminated.

What is Anal Itching ?



Anal itching is itching around your anus — the canal that's the outlet for your rectum. The itch, located in your anus or on the skin just around your anus, is often intense and may be accompanied by a strong urge to scratch. You may find anal itching to be an embarrassing and uncomfortable situation.

Also called pruritus ani, anal itching has many causes. Numerous factors may cause anal itching to be more intense — including moisture, abrasion caused by your clothing and the pressure of sitting.

Anal itching is a common problem that many people have experienced. Don't be afraid to talk with your doctor about this condition. With proper treatment and self-care measures, most people can achieve complete relief from anal itching.

Symptoms
Anal itching is associated with other similar symptoms in and around the anus, including :

* Burning
* Soreness or pain

The itching and irritation in and around your anus may be a temporary condition, or it can be a more persistent and bothersome problem. For some people, the irritation is so intense that the urge to scratch is both irresistible and embarrassing.

Causes
Most cases of anal itching are caused by a harmless problem. Occasionally, however, anal itching can be a sign of more-serious medical issues. Possible causes of anal itching include :

** Dry skin. As you age, skin in and around your anus is more prone to dryness. Dry skin can cause persistent, intense anal itching.

** Too much moisture. Moisture around your anus from excessive sweating or from moist, sticky stools can be irritating. Anal itching can also be caused by frequent diarrhea or the escape of small amounts of stool (fecal incontinence).

** Excessive washing. Excessive wiping with dry, harsh toilet paper or excessive scrubbing with harsh soaps can cause or aggravate anal itching. Failure to rinse away the soap completely also may cause irritation.

** Chemical irritants. Certain laundry soaps, colognes, douches and birth control products contain chemicals that can irritate skin in and around your anus. Scented or colored toilet paper can be irritating to people with sensitive skin.

** Food irritants. Anal itching may be the result of irritating chemicals in some foods, such as those found in spices and hot sauces. Similarly, some foods may directly or indirectly irritate your anus as they exit your colon. Common culprits include chocolate, alcohol, tomatoes, nuts and popcorn. Consuming certain beverages, including milk or caffeinated drinks, may cause some people to experience diarrhea followed by anal itching.

** Medications. Anal itching may be a side effect of certain medications, including some antibiotics, that can cause frequent diarrhea.

** Overuse of laxatives. Excessive or improper use of laxatives can lead to chronic diarrhea and the risk of anal irritation and itching.

** Hemorrhoids. Hemorrhoids are engorged veins located just under the membrane that lines the lowest part of your rectum and anus. They often occur as a result of straining during a bowel movement. Anal itching can be a symptom of hemorrhoids.

** Infections. Sexually transmitted diseases may also involve the anus and can cause anal itching. In children, the parasite that causes pinworms can cause persistent anal itching. Other parasites may cause similar itching.

** Skin disorders. Common skin problems — such as psoriasis, seborrhea and eczema — can involve and irritate the area in and around your anus.

** Yeast infections. This common infection, which usually affects women, can irritate your genital and anal areas.

** Anal abrasions and fissures. An anal abrasion is a small tear in your anus, usually caused by forced bowel movements through a tight anus. An anal fissure is a deeper tear. Both conditions can cause anal itching, as well as painful bowel movements and bleeding.

** Anal tumors. Rarely, benign or cancerous tumors in or around the anus may be a cause of anal itching.

** Other causes. Anal itching may be related to anxiety or stress. Sometimes, the cause remains undetermined.

Contributing to the problem
Although anal itching is almost never a problem of cleanliness, your own actions may contribute to the problem. Whatever the cause of anal itching, your natural reaction is to scratch the area. But scratching worsens the problem by removing superficial layers of skin. In addition, the natural tendency in response to an irritation is to wash the area frequently with soap and a washcloth. However, excessive washing can aggravate the condition by removing your skin's natural protective oils.

Most anal itching doesn't require medical care. However, see your doctor if :

* Anal itching is severe or prolonged
* There's bleeding from the rectum
* The itch can't be easily explained

Persistent anal itching may be related to a skin condition or other health problem that requires medical treatment.

What is Cholera ?

[Extracted from WiseGeek.com]

Cholera is a serious infectious disease caused by the bacteria Vibrio cholerae, which affects the intestinal system of the body. An infected person experiences severe vomiting, explosive diarrhea and severe dehydration. Without immediate medical treatment, cholera may result in death within four to twelve hours after symptoms begin. Due to a large loss of body fluids, cholera is gruesome in the way that it leaves survivors in their physical appearance, as well as in the biological toll it takes on the body.

Cholera is very contagious. It is spread by the unintentional consumption of infected feces that contaminate food and water. It can also be spread through human to human contact. Some people have been infected with cholera by eating raw or undercooked shellfish.

Cholera is easily treated with fluids and antibiotics. When antibiotics are unavailable, which is commonly the case in areas that are plagued by cholera, a simple mixture of water and glucose for rehydration is life saving. Cholera usually resolves itself after a period of time; the danger is the severe dehydration that quickly causes death.

Similar to the bubonic plague which has showed its face time and again, cholera is a plague that is suspected to be an ancient disease. It has unquestionably reoccurred in seven pandemics since 1817, including in Europe and the United States. The most recent pandemic began in Asia in 1961 and continues to the present day in Africa.

In developing countries, cholera is prevalent in areas that do not enjoy sanitary living conditions because of poverty and a lack of resources. In pandemic regions, even sanitary conditions may not prevent further outbreak. Many people do not receive information on how the disease is spread, fear seeking medical help or simply do not have access to any kind of treatment.

Cholera is not common in developed countries due to the availability of medical treatment, regulated heath standards, clean water and effective sewage systems. Cases of cholera in developed countries are the result of raw shellfish or people who have contracted the illness while traveling. Those traveling to countries that have cholera epidemics should take careful precautions to prevent infection.

Precautions for travelers include boiling water before drinking or washing. Water can also be treated with chlorine or iodine. Frequent hand washing with clean water, especially after using the toilet, is imperative. Travelers are also advised to ensure their food is fully cooked and hot, peeling their own fruit and avoiding raw vegetables, including salads. Raw and undercooked shellfish should also be avoided.

Cholera is a disease that causes social stigmas and stereotypes in epidemic areas. Indigenous peoples who commonly fall victim to cholera fear the status of social outcast more than the disease itself. Throughout history, communities that have had outbreaks of cholera are marked as diseased and dirty even after they are no longer at risk for spreading the disease.

What are Antibiotics ?

[Extracted from WiseGeek.com]

Antibiotics are medicinal products that have an anti-bacterial effect - they either kill bacteria in the system or keep them from reproducing, allowing the infected body to heal by producing its own defenses and overcome the infection. When antibiotics were isolated in the mid-twentieth century, they were widely hailed as 'wonder drugs' and indeed, formerly life-threatening infections could now be easily cured within a few days.

The most widely known antibiotic is perhaps penicillin, famously made from mold. When it was introduced, many of the sexually transmitted diseases such as gonorrhea went from being a shameful and life changing event to an embarrassing trip to the doctors.

One of the most prevalent and unstoppable myths about antibiotics is that they can cure a cold. Antibiotics work against bacterial infections, and colds are caused by viruses - therefore, a course of antibiotics will do nothing but perhaps kill off the body's own population of beneficial bacteria, leaving the cold to run its natural course. Nevertheless, patients often pressure their doctors into prescribing antibiotics when they come down with a cold or the flu.

One side effect of taking antibiotics for an infection is that it can leave the body defenseless against other non-bacterial types of infections, and for many women, this means a yeast infection, which is fungal. The fungus responsible for yeast infections is always present, and is kept from spreading by helpful bacteria in the digestive tract, which the antibiotics kill, or at least curtail, leaving the fungus to spread. Over-the-counter yeast infection products will usually work to alleviate a yeast infection.

Widespread use of antibiotics for non-medicinal purposes, such as in cattle feed and in antibacterial hand soaps, is causing concern in the medical and pharmaceutical industries, since it is responsible for the evolution of antibiotic resistant bacteria. Washing your hands with an antibacterial soap may make you feel cleaner, but any bacteria that survives the scrub is part of the bacterial population that is immune to that particular antibiotic, and thus all its descendants will be too. This has led to an "arms race" between bacteria and the drug manufacturers, with some antibiotics being held back or only minimally prescribed to prevent bacteria in the "wild" from adapting to them.

Antibiotics may seem like a recent innovation of the past hundred years, but indeed, many ancient civilizations had some understanding of the principle of antibiotics, and many herbs have anti-bacterial effects. One of the most widely known is common garlic. It is so effective at countering bacteria that over-consumption of garlic can have the same effect as antibiotics at leaving the body prey to non-bacterial infections by reducing the body's "good bacteria" population.

What is Vibrio Bacteria ?

[Extracted from RevolutionHealth.com]




What is Vibrio vulnificus food poisoning ?

Vibrio vulnificus food poisoning is caused by Vibrio vulnificus, a bacterium that lives in warm seawater. The condition is rare.

What causes Vibrio vulnificus food poisoning ?
Vibrio vulnificus food poisoning occurs when you eat seafood infected with the bacteria or you have an open wound that is exposed to them. The bacteria are frequently found in oysters and other shellfish in warm coastal waters during the summer months. People with weak immune systems, especially those with long-term (chronic) liver disease, are at greater risk for developing the condition than others.



What are the symptoms ?
In healthy people, Vibrio vulnificus food poisoning can cause vomiting, diarrhea, and abdominal pain. In people who have weak immune systems, the bacteria can infect the bloodstream, causing a severe and life-threatening illness. Symptoms include fever and chills, decreased blood pressure (septic shock), and blistering skin wounds. The infection is especially dangerous to people with long-term (chronic) liver disease.

If an open wound is exposed to the bacteria (such as from warm seawater), it may result in the skin breaking open and sores developing. People with weak immune systems are at risk for the bacteria moving into the bloodstream.

How is Vibrio vulnificus food poisoning diagnosed ?
Vibrio vulnificus food poisoning is diagnosed based on a medical history and a physical exam. Your health professional will ask you questions about your symptoms, foods you have recently eaten, and your work and home environments. If you have eaten raw seafood, especially oysters, your health professional may do a stool, wound, or blood culture.



How is it treated ?
You treat Vibrio vulnificus food poisoning by managing any complications until it passes. Dehydration caused by diarrhea and vomiting is the most common complication. In people with weak immune systems, or in people with severe symptoms, antibiotics may be used.

To prevent dehydration, take frequent sips of a rehydration drink (such as Lytren, Rehydralyte, or Pedialyte). Try to drink a cup of water or rehydration drink for each large, loose stool you have. Sports drinks, soda pop, and fruit juice contain too much sugar and not enough of the important electrolytes that are lost through diarrhea and should only be taken alternately with a rehydration drink.

Try to stick to your normal diet as much as possible. Eating your usual diet will help you to get enough nutrition. Doctors believe that eating a normal diet will also help you feel better faster. But try to avoid foods that are high in fat and sugar. Also avoid spicy foods, alcohol, and coffee for 2 days after all symptoms have disappeared.



How can I prevent Vibrio vulnificus food poisoning ?
The best way to prevent this type of food poisoning is to not eat raw oysters or other raw shellfish and to cook all shellfish (oysters, clams, mussels) thoroughly.

Boil shucked oysters at least 3 minutes, or fry them in oil at least 10 minutes at 375 F. For shellfish in the shell, either :

Boil until the shells open and continue boiling for 5 more minutes, or
Steam until the shells open and then continue cooking for 9 more minutes.
Do not eat those shellfish that do not open during cooking.

You should also :

* Avoid cross-contamination of cooked seafood and other foods with raw seafood and juices from raw seafood. Don't prepare them in the same place; and don't use the same cutting board when preparing them.

* Eat shellfish immediately after cooking, and refrigerate leftovers.

* Avoid exposing open wounds or broken skin to warm saltwater or brackish water or to raw shellfish harvested from such waters.

* Wear protective clothing, such as gloves, when handling raw shellfish.
