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?

The uterus or womb, is a muscular structure and is held in place by ligaments and pelvic muscles. If these muscles or tendons become weak, they cause prolapse and are no longer able to hold the uterus in its place.

Uterine prolapse happens when the uterus falls or slips from its ordinary position and into the vagina or birth waterway. It could be complete prolapse or even incomplete at times. A fragmented prolapse happens when the uterus is just hanging into the vagina. A complete prolapse depicts a circumstance in which the uterus falls so far down that some tissue rests outside of the vagina. Likewise, as a lady ages and with a loss of the hormone estrogen, her uterus can drop into the vaginal canal. This condition is known as a prolapsed uterus.

Risks: The risks of this condition are many and have been enumerated as follows:

    Complicated delivery during pregnancy
    Weak pelvic muscle
    Loss of tissue after menopause and loss of common estrogen
    Expanded weight in the stomach area, for example, endless cough, constipation, pelvic tumors or accumulation of liquid in the guts
    Being overweight
    Obesity causing extra strain on the muscles
    Real surgery in the pelvic zone
    Smoking

Symptoms: Some of the most common symptoms of prolapse involve:

    Feeling of sitting on a ball
    Abnormal vaginal bleeding
    Increase in discharge
    Problems while performing sexual intercourse
    Seeing the uterus coming out of the vagina
    A pulling or full feeling in the pelvis
    Constipation
    Bladder infections

Nonsurgical medications include:

    Losing weight and getting in shape to take stress off of pelvic structures
    Maintaining a distance from truly difficult work
    Doing Kegel workouts, which are pelvic floor practices that strengthen the vaginal muscles. This can be done at any time, even while sitting down at a desk.
    Taking estrogen treatment especially during menopause
    Wearing a pessary, which is a gadget embedded into the vagina that fits under the cervix and pushes up to settle the uterus and cervix
    Indulging in normal physical activity

Some specialists use the following methods to diagnose the problem:

    The specialist will examine you in standing position keeping in mind you are resting and request that you to cough or strain to build the weight in your abdomen.
    Particular conditions, for example, ureteral block because of complete prolapse, may require an intravenous pyelogram (IVP) or renal sonography. Color is infused into your vein, and an X-ray is used to view the flow of color through your urinary bladder.
    An ultrasound might be utilised to rule out any other existing pelvic issues. In this test, a wand is used on your stomach area or embedded into your vagina to create images of the internal organ with sound waves.

Uterine Prolapse: Risks, Symptoms and Diagnosis

When cells divide abnormally and uncontrollably, they can form a mass or lump of tissue. This lump is called a tumor. Bone tumors form in your bones. As the tumor grows, abnormal tissue can displace healthy tissue.

Some tumors are benign, meaning they aren t cancerous. While benign bone tumors won t spread to other parts of the body and are unlikely to be fatal, they can still be dangerous and may require treatment. Benign tumors can grow and could compress your healthy bone tissue. Other tumors are malignant, meaning they re cancerous. Malignant bone tumors can cause cancer to spread throughout the body.

Causes of bone tumor:

The cause of bone tumors is unknown. They often occur in areas of the bone that grow rapidly. Possible causes include:

Genetic defects passed down through families
Radiation
Injury
In most cases, no specific cause is found.
Symptoms of bone tumor:

Symptoms of bone tumor may include any of the following:

Bone fracture, especially fracture from slight injury (trauma)
Bone pain, may be worse at night
Occasionally a mass and swelling can be felt at the tumor site
Some benign tumors have no symptoms.
Diagnosing a bone tumor:

There are some common conditions like fractures, infections and other conditions that may resemble tumors. But, to be sure some physical examination to be performed which will check the tenderness in the bone and also the range of motion. Blood or Urine test may be performed to detect different proteins that may indicate the presence of tumor. Doctor may go with X-rays and depending on the X-ray results other imaging tests might be necessary i.e. CT scan, MRI PET scan. In some cases biopsy is also performed. In this test. a sample of the tissue that makes up the tumor is removed.

Treating bone tumor:

Bone cancer is generally treated with Surgery in which the entire tumor is removed. The surgeon carefully examines the margins of your tumor to make sure no cancer cells are left. Surgical techniques have improved greatly. Other ways to treat is radiation therapy which is used in conjunction with surgery. Still if the doctor feels that cancer cells are likely to spread or already spread then Chemotherapy is recommended.

Bone Tumor - How It Can Be Diagnosed?

Noncancerous growths of the muscle tissue surrounding the uterus are known as uterine fibroids. This is a common disease which about 70 to 80% of women contract by the time they are 50 years of age. The uterine fibroids can sometimes be very big and cause heavy periods as well as severe abdominal pain while at other times, uterine fibroids give no signs or symptoms whatsoever and go away on their own. This is why it is crucial to know what type of uterine fibroids you have and how to diagnose them. Here are the types of uterine fibroids and how to diagnose them;

Types
There are three main types of uterine fibroids. They are;

1. Intramural fibroids
The most common type of uterine fibroids are intramural fibroids. They typically appear in the endometrium and may grow larger which results in your womb getting stretched.

2. Subserosal fibroids
Subserosal fibroids are called so because they form on the serosa. The serosa is the outside of your uterus. Sometimes, Subserosal fibroids may grow so large that your uterus appears bigger on one side.

3. Pedunculated fibroids
Pedunculated fibroids tumors are basically Subserosal fibroids with a stem. A base which supports the tumor is called the stem.

Diagnosis
There are a number of tests done to diagnose uterine fibroids. They are;

1. Pelvic exam
A pelvic exam is a thorough inspection of a woman&#x2019;s pelvic area. The organs which are in the pelvic area include the cervix, ovaries, uterus and vagina. Normally, this and the next test in this article are enough to diagnose uterine fibroids.

2. Medical history
The history of your periods as well as the other symptoms you have will often be enough to diagnose the uterine fibroids. If your medical history is not enough, then you might need to undergo a pelvic exam.

3. Pelvic ultrasound
An ultrasound is when high-intensity sound waves are used to produce images of the pelvic area. This is only done when a pelvic exam and your medical history are not enough to diagnose uterine fibroids.

Types and Diagnosis of Uterine Fibroids

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!

Uterine cancer is also known as endometrial cancer. It is a cancer which begins in the lining of the uterus. The uterus is the part of a woman's body where the fetus develops. Uterine cancer is one of those rare cancers in India, which can be diagnosed in its early stages. This is because excessive vaginal bleeding occurs, thus making it a very serious and an apparent symptom. It is also one of the few forms of cancer which can be cured as removing the uterus is often more than enough to cure the patient of uterine cancer.

Here are the causes, diagnosis and treatment of uterine cancer:

Causes

The exact cause of uterine cancer is not yet known, however, there is a theory on what causes uterine cancer. Hormones in a woman's body have been thought to increase the chances of getting uterine cancer. This is because it has long been thought that having high levels of estrogen is the cause of uterine cancer. Increased estrogen thickens the endometrium and thus, increases the likelihood of uterine cancer.

Diagnosis

There are several tests used to diagnose whether you have uterine cancer including:

1. Pelvic exam: This is an examination in which the vagina, bladder, rectum and uterus are scanned for lumps. If they are found, it might be due to uterine cancer.
2. Pap test: A pap test is a special test designed to scan for uterine cancer.
3. Transvaginal ultrasound: A transvaginal ultrasound uses high-intensity sound waves so that pictures of the uterus can be taken.
4. Biopsy: During a biopsy, the doctor will remove tissue from the endometrium and it will then be analyzed for cancerous growths.

Treatment

1. Surgery: This is the most common treatment as it removes the entire uterus and prevents the spreading of the cancer.
2. Chemotherapy: Chemotherapy involves giving drugs which kill cancerous cells. They are given through either an intravenous line or even in pill form.
3. Hormone therapy: This is a therapy in which either progesterone levels are increased or estrogen levels are decreased.
4. Radiation therapy: In this treatment, high energy laser beams are used to destroy cancerous cells.
