Collectively grouped under the Ewing sarcoma family of tumors, Ewing's sarcoma is the second most common primary bone cancer occurring predominantly in children and in adolescents. Very rarely is it experienced in adults above the age of 30.

Typically forming in the bones of the chest, pelvis, head, back or trunk and in the long bones of the arms and legs, Ewing's sarcoma is believed to originate in certain kinds of primitive cells. When it begins to affect similar kind of cells found outside the bone, it is usually called an extraosseous Ewing's sarcoma.

Causes
1. Similar to all types of Ewing tumors, Ewing's sarcoma is generally caused by an alteration in a certain cell compelling a gene named EWS found on chromosome no. 22 to move over to a DNA section on any one of the surrounding chromosomes resulting in the activation of the EWS gene.
2. While it is not a hereditary condition, it usually occurs after childbirth, but no substantial evidence has been found as to why it happens so.

Symptoms
Symptoms of Ewing's sarcoma may include:
1. Swelling and pain especially in the arms, legs, back, chest or pelvis
2. Swelling accompanied by joint immobility
3. A bone breaks having no apparent cause
4. Swelling which may or may not be accompanied by a warm, tingling sensation
5. Fever resulting from unknown causes
6. Lumps or bumps which do not subside over time
7. Abnormal weight loss
8. High levels of fatigue
9. Tumors which have spread over to the lungs may cause shortness of breath
10.Tumors spread over to the spine may cause weakness or even paralysis.

Because the symptoms of Ewing's sarcoma can hardly be distinguished from symptoms caused by other infections or injuries, an early diagnosis is absolutely necessary for a successive treatment.

Causes and Symptoms of Ewing's Sarcoma

Liver transplantation or hepatic transplantation is the second most carried out transplant procedure in the world. It is a potentially difficult surgery that is performed by a team of two to four surgeons along with the help of anesthesiologists and nurses. It takes around 10 to 12 hours to complete the procedure as there are many anastomoses, sutures, reconnections, and disconnections, which are to be performed under the liver bed which is necessary for the transplant to be a success.

Tests required before a transplant is planned

Computed tomography, or CT scan which employs X-rays and a computer to create pictures of the liver, showing its size and shape. CTs and chest X-rays are also recorded to evaluate your heart and lungs.
Laser Doppler flowmetry: to check if the blood vessels to and from the liver are normal.
Echocardiogram to check the status of heart function.
Pulmonary function test or lung capacity test to study and determine the lungs' ability to exchange oxygen and carbon dioxide.
Blood tests are performed to determine the patient's blood type, clotting ability, and biochemical status of blood, and to determine liver function.
The liver transplant procedure

After an admission at the hospital, an Intravenous line is started in the patient's arm or hand. Other tubes (catheters) are put in their neck and wrist, or their collarbone or the area between the belly and the thigh (the groin). These are used to check heart and blood pressure, and to get blood samples.
The patient is placed on the back, over the operating table.
If there is too much hair at the surgical site, it may be shaved.
A catheter is placed into the bladder to drain urine.
After the patient is sedated, the anesthesiologist will insert a tube into the lungs. This is done so that the breathing can be helped with a ventilator. The anesthesiologist will keep checking the heart rate, blood pressure, breathing, and blood oxygen level during the surgery.
The skin at the surgical site will be cleaned with a sterile (antiseptic) solution.
The doctor will make a cut (incision) just under the ribs on both sides of the belly.
The doctor will carefully separate the diseased or the injured liver from the nearby organs and structures.
The attached arteries and veins are then clamped to stop the blood flow into the diseased liver.
The diseased liver will be cut off from the blood vessels and then removed.
The surgeon will check the donor liver before implanting it into the body.
The donor's liver is placed in the patient's body.
The incision will then be closed with sutures or surgical staples.

Liver Transplant Surgery - Understanding The Procedure!

The human body has 206 bones and bone cancer can affect any of these bones. This condition starts when healthy bone marrow cells mutate and grow out of control to form a tumor. There are many different types of bone cancer. Treatment of bone cancer varies from case to case and depends on factors such as, type of cancer, stage at which it is diagnosed and the patient s overall health amongst other factors.

Surgery, chemotherapy, and radiation are the three most common types of treatments favored for bone cancer. Surgery is usually used for low-grade tumors. This involves the removal of tumor and the surrounding healthy cells and tissues to ensure that that cancer does not recur. For high-grade tumors, surgery may be accompanied by chemotherapy, radiation or a combination of the two. 

Chemotherapy involves the delivery of medication to destroy cancer cells orally or intravenously. Radiation involves the use of high energy X rays to kill cancer cells. This is often used to treat patients with a tumor that cannot be surgically removed.

Apart from these standard forms of treatment, bone cancer patients are often advised to take part in clinical trials for their treatment. This can be described as a research study to test the efficiency of new approaches to the treatment of bone cancer. A clinical trial can be used to treat the safety and efficacy of a new drug, the new dosage of standard drugs or a new combination of treatment types. As a member of a clinical trial, you may be one of the first few people to benefit from treatment even before it is available to the general public. 

Some of the new options available through clinical trials are:

Immunotherapy: This is also known as biologic therapy. It is designed to boost the patient s immune system to fight cancer cells. Mifamurtidesi one of the types of immunotherapy being tested. Immune checkpoint inhibitors such as monoclonal antibodies are also being tested for their ability to block specific molecules.
Targeted therapy: This type of therapy targets the genes and proteins that contribute towards the growth and survival of cancer cells. Targeted therapy limits the damage caused to healthy cells and tissues and only blocks the growth of cancer cells.
Myeloablative therapy: This involves an intense regimen of chemotherapy. High doses of chemotherapy aim at destroying all the cancer cells. Unfortunately, in the process, healthy cells may also be killed. This may be followed by introducing stem cells through a bone marrow transplant to the patient s body to renew blood cells.
Intraoperative radiation therapy: These trials evaluate the use of radiation given inside the patient s body during a surgery. In cases where tumor is in a distant location of the body, stereotactic body radiotherapy and radiofrequency ablation may be used.


Bone Cancer - Understanding The New Approaches For Treatment!

Are you experiencing excruciating headache? you probably didn't know but you could be suffering from brain aneurysms. It is described as bulge formation in the blood vessel in the brain. It is a totally asymptomatic condition as one does not display any symptoms until the bulge vessel ruptures which may result in blood releasing in the skull which may further lead to a stroke. The bulge is often formed in the gaps between the tissues covering the brain and brain itself.

Most common treatment options for ruptured aneurysm
There are two common treatment options for a ruptured brain aneurysm endovascular coiling and surgical clipping. Both these procedures have certain risk factors, therefore it is best to discuss the details with a neurologist. The endovascular coiling is a less invasive process where the surgeon inserts a hollow tube or catheter into an artery and threads it through the body to reach an aneurysm. Then a guide wire is sent to push a soft platinum wire through the catheter. This coils up and disrupts the flow of blood into the aneurysm and leads to blood clotting. The clotting is essential in sealing off the aneurysm from the artery.

The surgical clipping is a process used for closing off the aneurysm, and a section of the skull is required to be removed for assessing the affected part. It also helps in locating the blood vessel that is responsible for the problem. Finally, a metal clip is placed on the neck of the aneurysm to stop the flow of blood. Though endovascular coiling is less invasive and said to be safer, adequate post-treatment care is necessary to minimize risks.
To treat larger aneurysms, a treatment called flow diverters may be useful. Since, the treatment is decided based on the size, location, apperance and your health condition, your doctor will be the best person to take the final call.

Other procedures to treat symptoms
Other than the surgical procedures several treatments might be prescribed to treat the symptoms and to manage complications. A few commonly advised treatments are:

Pain relievers: To manage headaches
Calcium channel blockers: One of the most common complications that may arise with an aneurysm is calcium entering the walls of blood vessels which may result in narrowing of walls. Calcium channel blockers are medications may be prescribed by the doctors to deal with the complication
Anti seizure medications: Medications such as levetiracetam, phenytoin, valproic acid, and others are prescribed to treat seizures associated with aneurysms
Procedures to prevent stroke: An insufficient blood flow may result in a stroke and to prevent it, the drug vasopressor is injected intravenously, or angioplasty is performed.
Rehabilitative therapy: Damage to the brain may require the patient to undergo several physical and occupational therapy.
If you suffer from the condition, it is advised to keep a check on the blood pressure and quit smoking as they can help in reducing the risks associated with aneurysms.

Brain Aneurysms - Key Treatments That Can Help With It!

All healthy individuals will always have some amount of urea in the blood. Yet, when the urea level in the blood becomes too high, that means there is a malfunction in some part of the body due to which the body is not being able to remove this excess urea successfully. This urea can be formed in the liver when there is a process in terms of the protein metabolism's chemical balance. This urea is then transported to various parts of the body until the kidney cleans it out as urine. But when this urea does not get cleaned out properly, the urea gets concentrated in the blood and signifies a problem with the kidneys and other internal organs as well as the blood flow to the kidneys. 

The cause may include burns, heart failure, renal artery embolism, vomiting and loose motions as well as more serious ailments like diabetes. This can lead to long term kidney damage and symptoms like thirst, fluid retention, headaches, fatigue, dizzy spells, accelerated pulse, restlessness in limbs, pain in the abdomen and more. Here are the best ways to reduce the blood urea levels in a natural manner.

Herbal medicines:

Ayurveda is an ancient science that can be used for the benefit of many patients suffering from chronic and painful ailments like diabetes, kidney failure, cardiovascular ailments and more. One of the mainstays of ayurveda includes the use of herbs to create medicines and concoctions that will help in giving relief with their 100% natural elements. Medicines like mutrakrichantak churna, punarnava mandur, varunadi vati and many others can be used to avoid dialysis and bring down the urea levels in the blood by aiding better functioning of the kidneys.

Punarnava: the name of this herb has been derived from two words - puna and nava. While puna means again, nava means new and together they help in renewed functioning of the organ that they treat. This herb helps in flushing out the excess fluid in the kidneys by reducing the swelling without any side effects. This herb is basically a kind of hogweed.
Varun: this is the common caper which can be used to break down the stones present in the renal region and even as a cure for urinary tract infection. This herb helps in removing any element that may be obstructing the urinary tract and finally removes the excess fluid build up and inflammation.
Gokshur: this is a diuretic that can be used as a herbal tonic to give strength to the weak kidney cells for regeneration.
Other aspects of ayurvedic treatment for this condition include proper protein intake and better hydration along with massages and yogic postures.

How to Reduce Urea Levels in Blood Naturally

The presence of a lump or a tumor in the breast is not always indicative of breast cancer. In some instances, the breast tumor can be benign or noncancerous as well. Thus, to understand breast cancer better, one should know the difference between a benign and malignant breast tumor. In this article, we will discuss the factors that differentiate a benign breast tumor from a malignant one.

Breast Fibroadenomas

Breast Fibroadenomas are benign breast tumors that often affect women in their early 20s and 30s (can also affect women of other age groups). Research suggests that in spite of being benign and noncancerous, breast fibroadenomas make a woman more susceptible to breast cancer in the future.
It may be difficult to decipher the underlying factor that triggers fibroadenomas. However, increased use of birth control pills (that results in an elevated estrogen level) can be a contributing factor.
Thus, in spite of no discomfort, it is safe to get fibroadenomas removed by lumpectomy or by radiation therapy. There are also instances when fibroadenomas dissolved on their own.
Sometimes, the lobules of the breast can undergo enlargement resulting in the formation of lumps (can be a tumor or a cyst) that are non-cancerous in nature. Such tumors are known as Adenosis.
The benign tumor growth can also develop in the milk ducts of the nipples, a condition known as  Intraductal papillomas (characterized by discharge from the nipples).
To stay safe and lower the risk of breast cancer, doctors often recommend the removal of the tumor.
Differences between Benign and Malignant Breast Tumors

One of the major factors resulting in a tumor is the abnormal growth of cells that could be triggered by an injury, an infection or prolonged inflammation.
A factor that plays a pivotal role in differentiating malignant from benign breast lumps or tumors is its ability to metastasize or invade other organs, cells and tissues of the body.
A malignant tumor starts off as a primary tumor that remains confined within its point of origin. Gradually, the cancerous growth metastasize, invading other neighboring as well as distant cells and body organs (Secondary cancer or tumor).
Benign tumors, on the other hand, contains chemical adhesions that prevent their metastasis and invasion to the other vital organs in the body.
As compared to malignant tumors, benign breast tumors, once removed, do not recur.
On the cellular level, microscopic examination reveals that malignant breast tumors often contain unusual, mutated, and modified genes and chromosomes.
More than often, malignant breast tumors give rise to Paraneoplastic Syndrome. The Paraneoplastic Syndrome is characterized by an elevated production of substances (can be antibodies or hormones) by the cancerous growths or tumors. The hormones or the antibodies circulate in the bloodstream and can alter the functioning of a host of vital body tissues and organs with deleterious health consequences.
Such things seldom take place in the case of benign breast tumors.
