Alexandra J. Golby, MD, Director, Image-guided Neurosurgery at Brigham and Women’s Hospital, discusses technological advancements to improve the precision of surgery to remove brain tumors.
It’s estimated that each year nearly 80,000 people are diagnosed with primary brain tumors and 100,000 with metastatic brain tumors. Nearly everybody is at risk for developing a brain tumor. Brain tumors can affect people from childhood to the last years of their lives. Men are slightly more affected than women and the causes of most brain tumors are not known.
There are a number of unique challenges in treating brain tumors. One challenge is that primary tumors can have indistinct margins that are difficult to see. Another challenge is that the tissue around a brain tumor is uniquely important and may impact things like language, visual and motor function.
The AMIGO Suite, opened in 2011 at Brigham and Women’s Hospital, is the Advanced Multimodality Image Guided Operating Suite. It's an NIH-funded national center which was developed with the goal of translating technological advances into improvements in surgical and interventional care for patients. In the AMIGO Suite, there is an intraoperative MRI scanner which can be brought in and out of the operating room during surgery to help surgeons visualize a patient’s tumor better.
Image-guided surgery uses the information obtained from advanced imaging and translates that into the planning and execution of surgery by acquiring high resolution and specialty structural images of the brain and also functional images of the brain. These images can be registered to one another and then to the patient's head during surgery. This allows surgeons to pinpoint the location of the tumor as well as the areas that we would like to preserve, areas that serve critical brain functions are located.
One of the big challenges, even with image-guided surgery, is that as we perform the surgery, the configuration of the brain is changing, and we call that brain shift. And it's due to changes in the brain itself and also as we remove tissue, things are constantly shifting and moving. When we're talking about doing brain tumor surgery, a few millimeters of movement can be a big difference. How to measure and track brain shift is an important area of research and a number of technologies are being studied to understand how to measure brain shift during surgery.
The development of various intraoperative imaging technologies allows surgeons to provide the most accurate surgical treatment for each individual patient.

Do you think you have a hernia?
What are hernias?
The hernias we address in this http://DoctorsExpressHartsdale.com Medical Minute are inguinal, or groin, hernias. More common in men than women, an inguinal hernia can occur when part of the small intestine protrudes through a weakness or tear in the area between your abdomen and your thigh- or your groin. It's possible for anyone to get an inguinal hernia, but it is more commonly found in males.
Hernias form a bulge and can be accompanied by pain. Men have an approximate 26% lifetime risk of having hernia at some point in their life, where as women have a much lower chance of one- only about 3% of women will experience a hernia at some point in their life. There are other types of hernias, such as abdominal, or "hiatal" hernias but groin hernias outnumber abdominal hernias by about 3 to 1.
What causes a hernia?
The cause of a hernia is not always known, but hernias are often the result of weak spots in the abdominal wall. Weaknesses can be due to congenital defects (present at birth) or formed later in life. Some risk factors for inguinal hernia include:
• fluid or pressure in the abdomen
• heavy lifting
• straining during urination or bowel movements
• obesity
• chronic cough
• pregnancy
Hernias often form in people with weakened abdominal muscles or in those who do a lot of heavy lifting or straining, which is why we see it quite often in young men. Physiology plays a part: men have testicles and scrotum which descend through the inguinal canal-much larger in men than in women. That is part of the reason men tend to be more susceptible to hernias than women.
Symptoms of hernia
Symptoms of inguinal hernia usually include a bulge in the groin area and pain, pressure, or aching at the bulge—especially when lifting, bending, or coughing. These symptoms usually subside during rest periods. Men may also experience swelling around the testicles.
Screening and Diagnosis of Hernias
If you are having abdominal pain or pelvic bulge and pain, you want to see physician, and he or she will do an exam. They will use their finger, to see if you have a bulge in your scrotum or on your groin and they'll see if its reducible or not. If the exam doesn't give them the answer, they can then perform an ultrasound, an inexpensive test that can tell you the same day whether a hernia is present.
What to do if you think you have a hernia
Most of the time hernias do not cause problems. People often live with hernias their entire life without them becoming aggravated or painful. When they do cause pain though, there is concern that complications may have arisen. Most common hernias are what we call reducible; you can take your finger or you can lie down in bed and due to the effects of gravity, the bulge in the groin will actually disappear, which means the intestinal contents actually go back into the abdominal cavity or to the correct location. If it's not reducible by lying down or using a finger or having a physician trying to reduce it, then there are concerns about complications such as strangulation, or incarceration occurring. If those concerns are there, then you need to see a surgeon, and there may be a need for surgery.
How to Treat a Hernia
As stated earlier, hernias can often be watched for years without being treated. If however, they are causing pain, we generally refer you to a surgeon who can do a very simple laparoscopic surgery.
If you suspect a hernia, but have not been diagnosed, you should see your doctor, and of course, we are happy to see you here at Doctors Express

http://www.nucleushealth.com/ - This 3D medical animation depicts two operations, called craniotomy and craniectomy, in which the skull is opened to access the brain. The normal anatomy of the skull and tissues surrounding the brain are shown, including arteries and veins. The animation lists the common reasons for these procedures, and briefly introduces intracranial pressure.
Video ID: ANH13109
Transcript:
Your doctor may recommend a craniotomy or a craniectomy procedure to treat a number of different brain diseases, injuries, or conditions.
Your skull is made of bone and serves as a hard, protective covering for your brain. Just inside your skull, three layers of tissue, called meninges, surround your brain. The thick, outermost layer is the dura mater. The middle tissue layer is the arachnoid mater and the innermost layer is the pia mater. Between the arachnoid mater and the pia mater is the subarachnoid space, which contains blood vessels and a clear fluid called cerebrospinal fluid. Blood vessels, called bridging veins, connect the surface of your brain with the dura mater. Other blood vessels, called cerebral arteries, bring blood to your brain.
Inside your skull, normal brain function requires a delicate balance of pressure between the blood in your blood vessels, the cerebrospinal fluid that surrounds your brain, and your brain tissue. This is called normal intracranial pressure. Increased intracranial pressure may result from: brain tumors, head injuries, problems with your blood vessels, or infections in your brain or spinal cord. These conditions put pressure on your brain and may cause it to swell or change shape inside your skull, which can lead to serious brain injury.
Your doctor may recommend a craniotomy to remove: abnormal brain tissue, such as a brain tumor, a sample of tissue by biopsy, a blood clot, called a hematoma, excess cerebrospinal fluid, or pus from an infection, called an abscess.
A craniotomy may also be done to: relieve brain swelling,
stop bleeding, called a hemorrhage, repair abnormal blood vessels, repair skull fractures, or repair damaged meninges.
Finally, a craniotomy may also be done to: treat brain conditions, such as epilepsy, deliver medication to your brain, or implant a medical device, such as a deep brain stimulator.
The most common reason for a craniotomy is to remove a brain tumor.

There are many symptoms that are associated with ulcers. Some ulcer sufferers only experience mild symptoms while others experience more severe. The more common symptoms of an ulcer are listed below. Abdominal discomfort is the most common symptom of an ulcer. This discomfort usually: is a dull, gnawing ache. • comes and goes for several days or weeks. • occurs 2 to 3 hours after a meal. • occurs in the middle of the night (when the stomach is empty). • is relieved by eating. • is relieved by antacid medications. Other symptoms include: • weight loss • poor appetite • bloating • burping • nausea • vomiting If you have some or all of these symptoms, it’s a good indicator that you may have an ulcer or be developing an ulcer.

Symptoms Burning stomach pain Feeling of fullness, bloating or belching Fatty food intolerance Heartburn Nausea The most common peptic ulcer symptom is burning stomach pain. Stomach acid makes the pain worse, as does having an empty stomach. The pain can often be relieved by eating certain foods that buffer stomach acid or by taking an acid-reducing medication, but then it may come back. The pain may be worse between meals and at night. Nearly three-quarters of people with peptic ulcers don't have symptoms. Less often, ulcers may cause severe signs or symptoms such as: Vomiting or vomiting blood — which may appear red or black Dark blood in stools, or stools that are black or tarry Trouble breathing Feeling faint Nausea or vomiting Unexplained weight loss Appetite changes
Site enhancement oil, often called "santol" or "synthol" (no relation to the Synthol mouthwash brand), refers to oils injected into muscles to increase the size or change the shape. Some bodybuilders, particularly at the professional level, inject their muscles with such mixtures to mimic the appearance of developed muscle where it may otherwise be disproportionate or lagging. This is known as "fluffing".Synthol is 85% oil, 7.5% lidocaine, and 7.5% alcohol. It is not restricted, and many brands are available on the Internet. The use of injected oil to enhance muscle appearance is common among bodybuilders, despite the fact that synthol can cause pulmonary embolisms, nerve damage, infections, sclerosing lipogranuloma,[60] stroke,[55] and the formation of oil-filled granulomas, cysts or ulcers in the muscle. Rare cases might require surgical intervention to avoid further damage to the muscle and/or to prevent loss of life. Sesame oil is often used in such mixtures, which can cause allergic reactions such as vasculitis.
Dr. Debbie Song at Gillette Children's describes in detail selective rhizotomy surgery.
A selective dorsal rhizotomy is an operation performed to treat spasticity. It is thought that high tone and spasticity arise from abnormal signals that are transmitted through sensory or dorsal nerve roots to the spinal cord. In a selective dorsal rhizotomy we identify and cut portions of the dorsal nerve roots that carry abnormal signals thereby disrupting the mechanisms that lead to spasticity. Potential patients go through a rigorous assessment that includes an in-depth gait and motion analysis as well as a physical therapy evaluation.
They are evaluated by a multidisciplinary team that includes a pediatric rehabilitation doctor, a neurosurgeon, and an orthopedist, Appropriate patient selection is vital. Ideal candidates for selective dorsal rhizotomy are children who are between four and ten years of age, have a history of being born prematurely, and have a diagnosis of diplegia cerebral palsy. These patients usually walk independently or with the assistance of crutches or a walker. They typically function at a level one, two, or three in the gross motor function classification system or gmfcs. A selective dorsal rhizotomy involves the coordinated efforts of the neurosurgery, physiatry, anesthesia and nursing teams. The operation entails making an incision in the lower back that is approximately six to eight inches long. We perform what we call a laminoplasty in which we remove the back part of the spinal elements from the lumbar one or l1 to l5 levels. At the end of the procedure the bone is put back on. We identify and open up the Dural sac that contain the spinal fluid spinal cord and nerve roots. Once the Dural sac is opened ,we expose the lumbar and upper sacral nerve roots that transmit information to and from the muscles of the lower extremities.
At each level we isolate the dorsal nerve root, which in turn is separated into as many as 30 smaller thread light fruitlets.
Each rootlet is then electrically stimulated. Specialized members of the physiatry team look for abnormal responses in the muscles of the legs as each rootless is being stimulated. If an abnormal response is observed then the rootlet is cut.
If a normal response is observed, then the rootlet is not cut. We usually end up cutting approximately 20 to 40 percent of the rootlets. The Dural sac is sutured closed and the l1 through l5 spinal elements are put back into anatomic position, thus restoring normal spinal alignment. The overlying tissues and skin are then closed and the patient is awoken from surgery. The entire operation takes between four and five hours. A crucial component to the success of our rhizotomy program is the extensive rehabilitation course following surgery. With their tone significantly reduced after a rhizotomy, patients relearn how to use their muscles to walk more efficiently through stretching, strengthening, and gait training. Approximately one to two years after a rhizotomy patients undergo repeat gait and motion analysis. The orthopedic surgeons assess the need for interventions to correct bone deformities, muscle contractures, poor motor control, impaired balance, or other problems related to cerebral palsy.
At Gillette we work closely with patients and families to ensure that our selective dorsal rhizotomy program meets their goals for enhancing their function and improving their quality of life.
