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 is set up inside the pelvis with different muscles, tissue, and tendons. Due to pregnancy, labour or complicated delivery, in a few ladies, these muscles tend to weaken. Additionally, as a woman ages and with a loss of the hormone oestrogen, her uterus can drop into the vaginal canal, bringing about the condition known as a uterine prolapse.

The following conditions can bring about a prolapsed uterus:

Pregnancy with complicated or even ordinary delivery through the vagina.
Weakness in the pelvic muscles with the increase in age.
Weakening and loss of tissue after menopause and loss of normal oestrogen.
Conditions leading to increased weight in the abdomen, for example, constant coughing (with bronchitis and asthma), straining along with constipation, pelvic tumours (uncommon), or clogging of liquid in the abdomen.
Being overweight puts extra strain on pelvic muscles.
Previous surgery in the pelvic region leading to loss of outer support
Smoking
However, this condition can be treated effectively:

Self care at Home: You can strengthen your pelvic muscles by performing Kegel workouts. You do these by contracting your pelvic muscles, as though attempting to stop the stream of urine. This exercise makes the pelvic muscle strong and gives some support. Have your specialist train you on the best possible approaches to exercise your muscles.
Medications: Oestrogen (a hormone) cream or suppository ovules or rings embedded into the vagina help in strength and endurance building of the tissues in the vagina. However, oestrogen is just for use in some of the postmenopausal ladies.
Surgery: Based on your age and whether you wish to conceive a child naturally, surgery can repair the uterus or remove it. The uterus as in many cases can be expelled with a hysterectomy. During the surgery, the specialist can repair the hanging or saggy vaginal dividers, urethra, bladder, or rectum. The surgery might be performed by an open abdomen procedure, through the vagina, or through little cuts in the abdomen or vagina with particular instruments.
Other Therapy: In case that you do not need surgery or have a poor possibility for surgery, you may choose to wear a steady gadget, called a pessary. It is worn in the vaginal tract to strengthen the falling uterus. It can be utilised briefly or can be long-lasting. They come in different shapes and sizes and should be fitted according to the person. In case that the prolapse is extreme, a pessary may not work. Prolapse surgery is always preferred by vaginal route. Likewise, pessaries can disturb the insides of the vagina and may bring about a noxious release.
It can be prevented in the following manner:

Decrease your weight.
Try to avoid constipation by consuming a high-fiber diet.
Do Kegel exercises to strengthen the pelvic muscles.
Stay away from heavy lifting or straining.

Prolapsed Uterus -  7 Conditions That Can Cause It!

Cancer of the kidneys is amongst the ten most common types of Cancer. There are many types of renal cancer with Renal cell carcinoma being the most common amongst them. Renal cancer is said to be triggered by a genetic mutation but the cause for this mutation is yet unknown. While kidney cancer appears suddenly in some cases, in others it is inherited from the parents. Here are 4 things you should know about cancer of the kidneys.

Risk Factors
Along with a mutation of the genes which is beyond our control, some lifestyle factors can also increase a person s risk of suffering from renal cancer. Some of these factors are:

Smoking
Obesity
High blood pressure
Symptoms
An early diagnosis can make the treatment of renal cancer much easier than if it is left undiagnosed. Hence, it becomes important to recognise the symptoms of this disease. Common renal cancer symptoms include:

Blood in the urine
A lump on either side of the abdomen
Persistent pain on one side of the abdomen
Tiredness
Unexplained weight loss
Fever
These symptoms are common to a number of other diseases as well and hence if you experience them, it is best to get yourself checked out by a doctor. In order to confirm a diagnosis, your doctor is likely to ask for blood tests, urine tests, an ultrasound and a CT scan or an MRI. In most cases, your doctor will also schedule a biopsy to check for cancer cells in the kidney tissue.

Stages of kidney cancer
Once cancer has been diagnosed, your doctor will need to determine the extent of damage caused in order to find the best form of treatment for the disease. Stages of kidney cancer are determined by the size of the tumour and on how much it has spread from the original location. There are four stages of kidney cancer.
Stage I   When the cancer cells are restricted to the kidneys and the tumour is no bigger than 3  in diameter
Stage II   The tumour has grown bigger in size but is still restricted to the kidney
Stage III   The tumour may be big or small but has spread to at least one lymph node or has affected the blood vessels
Stage IV   The cancerous cells have spread to nearby lymph nodes or other organs or the tumour has grown through the fatty layer and outer fibrous layer of the kidney.

Treatment
Kidney cancer can be cured easily if detected in the early stages by removing the tumour and adjacent tissue or the entire kidney if need be. Removing one kidney is not fatal as a person can live a healthy life with a single kidney.

Kidney Cancer - How Its Stages Can Affect The Treatment?

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.

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.

Know Everything About Uterine Prolapse!!

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.
