Rubbery cushions (discs) between the bones (vertebrae) stack up to form the spine. When a nerve between the disc and vertebrae is pressed and inflamed, that condition is called herniated disc. The herniated disc is also referred to as the ruptured disc or the slipped disc. This is caused when the soft jelly is pushed out due to a tear in the exterior. Herniated discs can lead to an irritation of the nerves and result in tremendous pain. It may also cause the arms and legs to become numb and weak. However, some people suffering from this condition may not display any symptoms at all.

Herniated disc generally occur in the lower part of the vertebral column. The herniated disc may also be seen in the thoracic spine or cervical spine. The symptoms of a herniated disc include pain in the legs, feet, or the buttocks, pain in the shoulder blade, tingling of the feet, numbness of the feet and hands, muscle weakness, neck pain or muscle spasm in the neck. Most common causes of herniated discs are aging, excessive weight or lifting of heavy weight.

Prevention of herniated disc

Herniated discs are very commonly found in people who are aged between 35 or 55 years. They are seen more commonly in the men in comparison to the women.
A herniated disc cannot be prevented easily, but there certain things that you can do to reduce the risks. Maintaining the proper techniques of lifting is important. You should not be bending at your waist. You should always bend the knees and keep the back straight. This helps you to use your leg muscles which are very strong to support the weight.
As the saying goes, precaution is better than cure, so here are few precautions that can be taken to avoid herniated discs. Practicing a proper posture can help in reducing the risk of a herniated disc. It is extremely important for an individual to maintain a healthy posture while standing, sitting, walking, and even sleeping. It is imperative that you stretch your muscles when you are sitting in one position for a long time.
Another important thing to avoid is high-heeled shoes, as they are few of the most common causes of a herniated disc. It would be a good idea to go for flat and well cushioned comfortable footwear as they can go a long way in reducing the risk of the herniated disc.
Exercising regularly can go a long way in keeping the muscles of the legs, stomach, and back very strong. You should try to balance your flexibility and strength by exercising regularly. The best form of exercise to avoid herniated disc or ruptured disc is aerobic exercise.
It is true that as you start to age, the chances of getting a herniated disc increase significantly. However, if proper precautions are taken, the stress put on the spine can be effectively reduced, thereby eliminating the risk of a herniated disc. 

Herniated Disc - Is There A Way It Can Be Prevented?

Brain mapping is a technique where the biological quantities of a human brain are represented as spatial quantities resulting in maps. As with many other medical technologies, brain mapping is fast-evolving as well. Among several uses, brain mapping is chiefly used while performing surgery on the brain.

When surgery is to be performed on the brain such as surgery for epilepsy, the surgeon would want to comprehend how the brain areas are affected by seizures. The surgical intervention is meant for removing as much as seizure focus as possible while preserving crucial functions like understanding, speech, vision, movement, and sensation.

Why is brain mapping performed?
Brain mapping is a process which helps in identification of functions of various parts of the brain. Mapping the brain by stimulating different areas of the brain areas can aid in creating a map for a particular person. The map allows the doctor in understanding what parts of the brain are responsible for performing critical functions including sensation, movement, speech and other functions.

Which functions of the brain can be mapped electrically?
Typical areas of the brain which have motor, language, visual and sensory functions are needed to be mapped. When current is applied to a single area at a time, the doctor understands which part of the brain is responsible for which function.
When the patient is not able to speak due to the current, then the area is likely to be crucial for language function. If the limbs, face or trunk of the patient stop moving as the current passes, the area that is tested is responsible for movement. On the other hand, if the individual experiences tingling, numbing, and other sensations when the current is applied, it means that a sensory region is discovered.

How is electrical brain mapping performed?
Electrical brain mapping for guiding brain surgery for epilepsy can be performed in two distinct processes: directly during the surgery or in a two-stage procedure.

Two-stage procedure:
In the first stage of the process, the surgeon creates an opening in the skull which helps in exposing the surface of the brain. Small electrical contacts or electrodes are placed on the brain surface even though no brain tissue is removed. As soon as the electrodes are in the right position, the scalp is closed. The electrodes not only record the seizure of the patient electrically but also allow mapping of various areas of the brain. The last stage is surgery where abnormal brain tissues are removed.

Brain mapping process during surgery:
Electrical brain mapping may also be performed during the surgery which exposes part of the brain. This is termed as intraoperative brain mapping since it occurs while performing the main operation. The process of mapping may last for an hour to several hours at a stretch.

Brain mapping is also used to diagnose neurodegenerative diseases like Alzheimer s and Parkinson s. In these cases, the brain map shows extreme shrinkage of the brain due to tissue loss.

Brain Mapping Surgery - Why It Is Performed?

Even though brain aneurysms are becoming common these days, not all of them are required to be treated. In some cases, the physician may choose to observe an aneurysm closely before adopting any treatment measure. But in patients in whom an aneurysm has progressed to a severe level, there are two treatment options:

Open surgical clipping
Endovascular therapy or coiling
Open surgical clipping for brain aneurysms:
This procedure is typically performed by a neurosurgeon who makes an incision in the head. An opening in the bone is made, and then a clip is positioned by dissecting through the spaces of the brain. This aids in preventing the flow of blood into an aneurysm. In this procedure, the patient is required to stay in the hospital for two to three nights after which he or she is discharged.

Considerable modifications have been made in the open surgery techniques in the recent years. Neurosurgeons are now able to perform eye brow incisions or mini craniotomies for clipping an aneurysm. In these procedures, a small incision is cut out in the skin above the eyebrow for making a window. A tiny clip is placed across the mouth of an aneurysm to help it heal. But it is worthy of mention here that these are all invasive procedures and take relatively longer time to recover compared to the coiling process.

Endovascular coiling:

This treatment is also performed by a neurosurgeon, and it has been proved that this process is exceptionally suitable for patients with a ruptured aneurysm. Endovascular coiling is often done in coalesce with an angiogram, where a catheter is inserted into the vessel over the hip, which is then gradually carried to the vessels of the brain and finally to an aneurysm.
Then the coils are packed to the point where it rises from the blood vessel, which prevents the blood from flowing intothe blood vessel. Most patients undergoing this minimally invasive procedure can go home the day following the surgery. The success rate of this process is very high, and over 125,000 patients have been treated all across the globe with the help of detachable platinum coils.
Over the last few years, a substantial amount of advancements have taken place in the endovascular techniques. Recent developments show the use of flow diverting embolization devices, which are similar to a stent and are placed in the primary vessel, adjacent to an aneurysm. It diverts the flow away from an aneurysm and therefore, allows the neurosurgeons to treat the brain aneurysms, which were previously considered inaccessible and untreatable.
Both the procedures are quite efficient in treating a brain aneurysm. The most suitable option is dependent on a host of factors such as size, shape, location and overall health condition of the patient.

Brain Aneurysms - Treatment Options Available For It!

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!

Chemotherapy has been the remedy for cancer since the late 90s. But in today s world the medical field has been improved so much that new methods have been invented. One of them is Hormonal therapy. It is used to cure some types of breast cancer that are affected by hormones. Receptor proteins in the breast cancer cells attach to estrogen and help the cells grow. This therapy stops the receptors attaching to estrogen in various ways.

When it is used?
Hormonal breast cancer therapy is performed after surgery to prevent the cancer from coming back. It is also applied to treat the cancer that has come back or to prevent the cancer from spreading to other parts of the body. Sometimes, if needed, it starts before the surgery. It takes five years, generally.

How it works?
Hormonal therapy mainly stops estrogen from acting on the cancer cells or lowers the estrogen level. There are different ways to do that.

Blocking Estrogen Receptors: These drugs stop estrogen from helping breast cancer cells.
Tamoxifen: It acts as anti-estrogen in the breast cells, but acts like estrogen in other cells. It lowers the risk of breast cancer and also stops cancer from coming back.
Toremifene: It works in a similar way, but it is only used in metastatic breast cancer. It also decreases the pain and swelling in the muscles and bones.
Fulvestrant: It blocks and damages estrogen receptors. It is given by injections after other drugs stop working.
Lowering Estrogen Levels: These drugs slow the growth of cancer by lowering estrogen levels.
Aromatase Inhibitors: These drugs stop estrogen production in women whose ovaries are not working due to menopause or other treatments. There are three types of this drug- Letrozole, Anastrozole and Exemestane.
Ovarian Suppression: In this method, ovaries are removed or shut down to turn pre-menopausal women to post-menopausal. There are several ways to do this, and they are- Oophorectomy or surgery, LHRH analogs and applying chemotherapy drugs.
There are some other types of hormone therapy that are less common. They were used more in the past. They are:

Megestrol acetate
Androgens
High doses of estrogen
Side Effects:
Unfortunately, Hormonal breast cancer therapy has lots of side effects. They are-

Hot flashes
Mood swings
Vagina discharge or dryness
Developing uterine cancer
Blood clots
Stroke
Night sweat
Headache
Mild nausea
Bone pain
Injection site pain
Muscle pain and joint stiffness and pain
Bone thinning
Menopause
Although hormonal therapy has lots of side effects, they are limited to different kinds of hormonal therapies and it is not necessary that they will surely happen. But it is best to undergo any kind of treatment with a doctor s advice. So patients should consult the doctor first.

Breast Cancer - New Advancements That Can Help!

A mammogram is an imaging test where an X-ray is taken to recreate the internal imagery of your breasts. This is a screening test that is widely used to find the earliest signs of cancer. There have been instances where the early signs of cancer have been found up to three years before the actual development of the same. There are a number of benefits and risks in this screening method. So let us find out more about getting a mammogram, and whether or not you should get one.

    Procedure: A special X-ray machine is used for conducting a mammogram. There is a clear plastic plate on which the specialist will place the breast while another plate will press on the breast from above. While both the plates serve to flatten the breast and hold it still, the X-ray will be taken. Some pressure will be felt and the same steps will be repeated so as to get the side view of the breasts. The same procedure will be repeated for the other breast. Meanwhile, once it is done, you will need to wait so that the technician can check for clarity, and whether or not the procedure needs to be done again. The results of this procedure cannot be relayed by the technician, and all the images will be different because all breasts are slightly different from each other.
    Preparation: You will need to remember that the process can be a slightly painful one, especially once the pressure gets applied. Many women complain of discomfort and pain. Yet, this discomfort gets over before you know it. The pressure and pain will depend on the size of your breasts and how much they will have to be pressed in order to get a picture. The skill of the technician will also come into play here. One must remember not to get this procedure done a week or so before or after the menstrual cycle, as the breasts tend to be tender around this time, and the pain will be much more.
    Radiologist: Within a few weeks after the procedure, the radiologist will usually deliver the result. This is the professional who does an accurate reading of the X-ray.
    Normal and Abnormal Readings: If your mammogram result has a normal reading, then you can resort to getting one done every once in a while. But an abnormal reading will require further X-ray and tests so as to be able to tell for sure.
    Why should I get one: If you are over 40 and have a family history of such ailments, then you will have to get a mammogram done regularly.
