Gamma Knife surgery for focal brainstem gliomasCHUN PO YEN, M.D., JASON SHEEHAN, M.D., PH.D., MELITA STEINER, M.D.,GREG PATTERSON, R.N., B.S.N., AND LADISLAU STEINER, M.D., PH.D.This is a great report on Gamma Knife Surge ry (GKS).The progress that is being done on tumors that are located in these sensitive areas close to the middle of the brain or brainstem is wonderful for patients. These Doctors are able to shrink the tumors using Gamma Ray technology.

Frank G. Shellock, PhD, FACC, Has once again been at work Testing more devices to make sure they are MRI SAFE. I don't know if the day will ever come that we will be scanning pacemakers on a routine basis, but it seems to get closer every year. Here is the most recent publication from Dr. Shellock. Cardiac Pacemakers and Implantable CardioverterDefibrillators: In Vitro Magnetic Resonance ImagingEvaluation at 1.5-Tesla

3 LBS ...........................;)

Now this is a show I can watch. I like to watch the medical shows, I don't know why, I would think that when I got home I would like to leave work behind me. The thing is these characters on the shows are always doing crazy things we could never dream of doing in real life. I don't know if you have ever seen Grey's Anatomy but this show is so Dramatic. I love it, but it is not real. Another show that is very entertaining because of the brilliant acting of Hugh Laurie. He is a one man show in House. The only complaint about House is that they exaggerate allot. The MRI machine need I say more.................. If you are an MRI tech or have had an MRI you will understand how ridiculous they make themselves look when they are doing MRI's. The time that I am thinking about is when they had a 600lb patient that had to be done even though he exceeded table weight limit. They were too worried that they might get sued if they didn't try to do the patient. MY GOD, give me a break. I wou...

SilverHawk™ Plaque Excision System
2006-11-21 00:02:00
This is the future, FoxHollow Technologies Inc.'s Silver Hawk catheter is one of the hottest selling new medical devices on the market and has sent the company's stock surging since it went public in October 2005. Titusville, Fla. (July 14, 2006)— Parrish Medical Center (PMC) recently started doing a new procedure to help fight peripheral artery disease (PAD) using the SilverHawk™ Peripheral Plaque Excision System and SilverHawk™ Cutter Driver — devices that remove the plaque that commonly blocks arteries and interrupts blood flow. Since March 2006, Radiologist Joseph Flynn, D.O., and the Interventional Radiology department at Parrish Medical Center have been successfully performing this procedure. Dr. Flynn is continually advancing his knowledge to bring cutting-edge technology to the North Brevard community through advanced classes and seminar training. Other Interventional Radiology care partners are Tammy Flannery RT(R)(CT)(CV), Jennifer Rice RT(R), Julie Cook R.N. and ...

The Pituitay, Empty Sella, & Ruptured Aneurysms
2006-11-05 19:39:00
The Pituitary is such a small part of the brain, about the size of a pea, and yet in controls so many functions. Its main function is to control the release of hormones throughout the body. The Pituitary is is conected to the hypothalmus by nerve fibers. There are several hormones that the pituiatry control the release of:ProlactinMelanocyte-Stimulating Hormone (MSH)Gonadotropins: Luteinizing and Follicle Stimulating HormonesAdrenocorticotropic Hormone (ACTH, corticotropin)Growth Hormone (Somatotropin)Follicle-stimulating hormoneEmpty sella syndrome occurs in patients when spinal fluid is found within the space created for the pituitary. The most common cause is a large openening a membrane which sits on top of the pituitary. When this opening is large, the spinal fluid pressure is forcred down onto the pituitary and flattens it out within the sella. In most cases, the pituitary functions normally as evidenced by normal thyroid functions, normal tests of adrenal function, normal som...

Brain Aneurysms
2006-11-02 01:32:00
The Brain is an amazing thing but when things go wrong it sure gets scary. When a person has an aneurysm they can go for years without knowing it. It is only when they start to experience new symptoms that they start to wonder what is going on. Some of these symptoms include loss of feeling in the face or problems with the eyes. Immediately before an aneurysm ruptures, an individual may experience such symptoms as a sudden and unusually severe headache, nausea, vision impairment, vomiting, and loss of consciousness. I have a friend at work that came in with several of these symptoms one day and now she has 2 aneurysm clips in her cerebral arteries. She had the clips put in at Shands in Florida. There are other methods including embolization coils to fix aneurysms. Many MRI centers will not scan a patient with a Aneurysm clip in their brain, but will scan a patient with embolization coils. CTA's of the brain are another great way to see the cerebellar arteries at little risk to the ...

Mirror Neurons & Autism
2006-10-31 02:33:00
Have you ever seen someone take a bite out of a red juicey apple and almost tasted it youself. That is the work of your "mirror neurons" doing their job. They were first discovered in the early 1990s, when a team of Italian researchers found individual "mirrror neurons" in the brains of macaque monkeys that fired both when the monkeys grabbed an object and also when the monkeys watched another primate grab the same object. Disgust, embarassment, and lust are based on a uniquely human mirror neuron system found in a part of the brain called the insula.There has been new research done into the area of these mirror cells and Autism . Ever since autism was identified It has been a struggle to find out what causes it. We know It can be inherited, but the enviroment may also play some part. In people with autism their main signs are lack of eye contact and absence of empathy. They may also have problems understanding metaphors, sometimes taking them literally. Another very unusual behavior...

WHEN THE BONE FLAP HITS THE FLOOR
2006-10-12 05:05:00
I Had to post this .............I saw this Info online I thought I would Share with everyone.When the Bone Flap Hits the Floor . Neurosurgery. 59(3):585-590, September 2006.Brian T. Jankowitz, M.D.; Douglas S. Kondziolka, M.D.Links: Abstract HTML PDF (447 K)Abstract: OBJECTIVE: There is no published data in the neurosurgical literature describing the incidence, treatment, or outcome of contaminating a bone flap. We reviewed our departmental experience to determine methods of prevention and assess our treatment strategies.METHODS: We retrospectively reviewed all incidents of dropped bone flaps during a craniotomy at a single medical center during a 16-year period. In addition, a questionnaire was mailed to neurosurgeons in the United States and abroad asking their own experience and method of management.RESULTS: Fourteen incidents of dropped bone flaps occurred during a 16-year period. Follow-up varied from 2 to 176 months. The bone flap was dropped while elevating the bone (n = 4), w...

Rare and unusal cases (Erdheim-Chester Disease)
2006-09-29 15:05:00
Recently, I had a patient come in for a Brain MRI. She had Erdheim-Chest er disease. It is a type of histiocytosis. This disease is a rare non-Langerhans cells histiocytosis affecting multiple organ systems . Symmetric sclerosis of the long bones is usually reported, but the central nervous system and sinus can also be affected. Among patients with central nervous system involvement, the most frequent manifestations are diabetes insipidus, cerebellar syndromes, orbital lesions, and extra-axial masses involving the dura . The patient is coming in to be scanned about every 6 months. She is on cobalt and it seems to be helping. Her chemotherapy looks like it is making her very weak, but seems to be helping the disease. I was supprised at how little information there was about this disease on the web when I started looking. I did find one source of information that recomended doing a T2 flair cor in addition to the T2 flair ax. I am glad I did because the lesions in her brain show up bet...
