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.
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. If you wish to discuss about any specific problem, you can consult a Neurosurgeon.
What is Bone cancer?
Bone cancer is malignant tumour of the bones which can spread to lungs or other parts of the body. It may have arisen primarily from the bone itself (primary bone cancer) or more commonly, may have spread to the bones (secondary bone cancer) from cancer of some other body organ like Breast cancer, Prostate cancer etc.
Primary bone cancer usually occurs in growing children and young adolescents, whereas, secondary bone cancer usually occurs in older age group. Usually, the patient experiences pain in the affected area, which over the time, gets worse and continuous. There may also be swelling in the involved region. It can cause weakening of bones resulting in fracture. Some patients may attribute these symptoms to any prior antecedent trauma. Unintentional weight loss may also be seen. Sometimes, these patients are wrongly being treated for infection, thus delaying the correct treatment which may have a bearing on the final outcome.
How common is bone cancer?
Secondary bone cancer is the most common type of bone cancer with bone being the third most common site of cancer spread (metastasis) from other organs. However, primary bone cancers are rare accounting for less than 1% of all cancers.
Causes of bone cancer?
There are no known environmental or other hereditary factors which cause bone cancer, however, certain patients are at a greater risk for bone cancer which include:
- Patients who have received prior radiation therapy
- Patients with a history of Paget’s Disease
- Patients with hereditary retinoblastoma - a type of eye cancer that most commonly affects very young children
- Patients with Li-Fraumeni syndrome - a rare genetic condition
How is it diagnosed?
A patient suspected with bone cancer needs to be investigated thoroughly with blood tests, Xrays, MRI to look for local extent of disease. Since bone cancer can spread to lungs and other bones, staging of the disease is done either with whole body PET CT or a bone scan with CT Chest. Alongwith that, a biopsy (usually with a needle) is required to establish the diagnosis. It’s important to do biopsy from the correct site since wrong biopsy site can be detrimental in limb salvage and can result in amputation (cutting the limb). Therefore, it’s recommended that the biopsy should always be done by the surgeon (Orthopaedic Oncologist) who will be doing the final surgery for bone cancer.
Treatment of bone cancer is a multidisciplinary approach requiring an Orthopaedic Oncologist (Bone & Soft tissue tumour specialist), Medical Oncologist (Chemotherapy Specialist), Radiation Oncologist (Radiotherapy specialist) and Pathologist (Specialist in tissue diagnosis).
Usually in primary bone cancers, chemotherapy is given to the patient followed by surgery to remove the diseased bone which is further followed by adjuvant chemotherapy. Limb salvage surgery is possible nowadays for bone cancers in which the part of the bone involved with tumour is removed surgically (rather than cutting the whole limb) and the defect is reconstructed with artificial joint, thereby saving the limb. In some cases, the cancerous bone so removed is given very high dose of radiation so as to kill all the cancer cells and the sterilised bone so formed is fixed back to the parent bone with the help of plates and screws, a technique commonly called as Extra Corporeal Radiation Therapy (ECRT). In children, since the artificial joint will not grow as the child grows leading to unequal limb lengths over a period of time, the defect can be reconstructed with expandable joint which can be lengthened as the child grows which allows to maintain limb length equality at the time of skeletal maturity.
Is cure possible in bone cancer?
With the current chemotherapy regimes and advanced surgical technology, cure is possible in upto 70-75% patients with primary bone cancer. In patients with secondary bone cancer, cure can still be achieved depending upon the primary cancer and the extent of disease. In advanced cases also, a lot can be done to control the disease and give a quality of life to the patient.
Is it possible to prevent bone cancer?
Since the exact cause of bone cancer is not known, as of now it’s not possible to prevent bone cancer.
Whom to consult?
First chance is the best chance when it comes to curing bone cancers. So, it’s advisable to seek treatment from a trained Orthopaedic Oncologist when confronted with a bone cancer to achieve maximum beneficial outcome.

I am 33 years old, I have backache from last 1 year, x ray indicate there is borderline slip disk, what kind of precaution can I take for future?
Arguably one of the most fatal diseases that threaten human life, Meningitis has been the cause of a lot of recent deaths. Essentially Meningitis is triggered off by the anomalous inflammation of the protective membranes called meninges in the brain and spinal cord. Spurred by some sort of a bacterial or viral attack, this condition emanates from an infection of the fluids in the cranial chamber. Often such conditions are also stimulated by some external injury, cancerous development or even certain kinds of reaction from a given drug or the other.
Depending on the precise cause of the disease, Meningitis may be categorized as Bacterial Meningitis, Viral Meningitis or Fungal Meningitis. Other forms of Meningitis include parasitic Meningitis, Amebic Meningitis and Non-Infectious Meningitis. Meningitis could potentially be contagious. Through lengthy and proximal contact like coughing or kissing, if saliva or spit gets exchanged, Meningitis causing germs may spread from one person to the other.
Streptococcus pneumoniae and Neisseria Meningitidis are the two of the most rampant Meningitis causing bacteria. They have the potential of causing irreversible damage to several vital organs. However, with substantive progress in medical science, effective and suitable medication has been made available to the larger populace. But, immediate attention is imperative in this case.
Viral Meningitis is relatively milder than the other forms of meningitis. Enteroviruses, arboviruses and herpes virus are some of the most common sources of this kind of Meningitis. People with strong immunity are usually able to overcome this without much ado. Vaccines are available widely in the markets to cure viral meningitis.
Fungal Meningitis are caused primarily from external influences. Inhaling fungal spores from the environment is one of the most prominent factors that lead to Meningitis. People suffering from fatal diseases like cancer, diabetes or HIV are more susceptible to fungal Meningitis. While these are a few of the primary forms of meningitis, other triggers to this disease occur due to various environmental interventions. These are consequent upon interactions with various disease causing allergens. Cure to meningitis is available in the form of intravenous injections. But timely diagnosis and treatment is essential for a good outcome. If you wish to discuss about any specific problem, you can consult a pediatrician.

What is ECMO?
Like dialysis for unfunctional kidney, Ecmo for unfunctional lung.
Ecmo stands for extracorporeal membrane oxygenation. It is a method of giving oxygen for the body when icu pateint lungs and/or heart are not able to supply oxygen on their own.
Why ICU pateint put on ECMO?
Doctors place ICU patients on ECMO when patients are not able to supply oxygen to the body.
ICU patients’ lungs fail for a number of reasons including pneumonia, lung cancer, pulmonary edema, pulmonary embolism and COPD.
When a patient’s lungs fail, he/she first is intubated (breathing tube) and hooked up to a ventilator (breathing machine).
However, sometimes lungs are so damaged that providing oxygen through intubation is not enough.
This is when doctors turn to v-v ecmo.
A heart can fail for many reasons including heart attack, pulmonary embolism, bad valve disease, or worsening heart failure. When a heart fails, doctors try to fix the underlying problem. They may also start medications (called ionotropes) to help improve the pump function of the heart. If medications are not enough, doctors will turn to v-a ecmo.
How long can someone stay on ecmo?
That is a complicated question. Due to the risks of ecmo discussed above, doctors try to keep patients on ecmo for as short a time as possible. Often patient will be on ecmo for several days up to 1-2 weeks. Every day, several blood and imaging tests are done to determine if a patient is ready to come off ecmo. As the technology of ecmo improves, hopefully side effects will decrease and patients can remain on ecmo for longer periods of time.
What is the difference between ecmo and a ventilator (breathing machine)?
Both ecmo and a ventilator aim to provide oxygen to the body when the patient’s own lungs and breathing are failing. The ventilator assists the patient’s own lungs by pushing oxygen with pressure into the lungs. Ecmo instead provides oxygen directly via a catheter placed in a patient’s vein or artery. We almost always try oxygenating a patient with a ventilator first. However, when a patient’s lungs are too sick for this, we turn to ecmo to assist in providing oxygen to the body. V-v ecmo provides oxygen through a vein. This blood then has to travel to the heart and be pumped around the rest of the body through arteries. Therefore, with v-v ecmo or with a ventilator, a patient must have a well-functioning heart to get the oxygen pumped throughout the body. V-a ecmo has the additional advantage of pumping blood directly to arteries. This “by-passes” the heart and is therefore the method of ecmo we use when a patient’s heart is failing.
