Gamma Knife Surgery – Have Brain Surgery, Be Dwelling in Time For Dinner

Gamma Knife Surgery is not truly surgery as you know it. There is no knife, no scalpel. Why did they name it Gamma Knife Surgery? Beats me. But I can inform you it is an successful tool. Take it from an individual who has had their head opened up far more than the moment. Gamma Knife individuals often waltz out of the hospital the exact same day and nonetheless have their hair. I walked, or rather walked gingerly to my automobile the week when every of my craniotomies. And my head was shaved which did not qualify me as a style diva. So it is really worth the work to see if your brain tumor or brain disorder qualifies for gamma knife surgery.

Neurosurgery for OCD patients

Psychosurgery is used for the patients of OCD problems and it is only a sub sect of the neurosurgery or surgery for the brain. It is mostly used for patients who do not respond to any other form of treatment and therapy. In olden days, lobotomy was used which has now been replaced with psychosurgery. Lobotomy has been found to damage the brain and there have been cases of memory loss. Psychosurgery disables a part of the brain with the help of electrodes. The area to be disabled is selected with the help of magnetic resonance imaging. Around one third of the patients have reported improvement.
Novel techniques of gamma knife irradiation and the deep brain stimulation have come up as the modern form of neurosurgery. With so much of advancements in the treatments for various illnesses conventional treatments for the OCD has resulted in only temporary relief that too in 20 % of the patients only.

American Shared Hospital Services Reports Second Quarter Results

SAN FRANCISCO, Aug 08, 2011 (BUSINESS WIRE) -- AMERICAN SHARED HOSPITAL SERVICES /quotes/zigman/217821/quotes/nls/ams AMS -3.18% , a leading provider of turnkey technology solutions for advanced radiosurgical and radiation therapy services, today announced financial results for the second quarter and first half of 2011.

Second Quarter Results

For the three months ended June 30, 2011, revenue increased 1.2% to $4,206,000 compared to $4,155,000 for the second quarter of 2010. Net income for the second quarter of 2011 rose to $21,000, or $0.00 per share. This compares to net income of $3,000, or $0.00 per share, for the second quarter of 2010.

The number of procedures performed on Gamma Knife(R) Perfexion(TM) systems supplied by AMS increased 10.3% for the second quarter of 2011 and 15.9% for the first half, compared to the second quarter and first half of 2010, respectively. The total number of procedures performed in AMS' Gamma Knife business decreased 3.1% for the second quarter and increased 4.1% for the first half, compared to the second quarter and first half of 2010, respectively.

The primary reason for the decrease in total Gamma Knife procedures in the second quarter was that the Gamma Knife unit at Lehigh Valley Hospital in Allentown, Pennsylvania is being held for sale and AMS no longer gets credit for procedures performed there. In March 2011 AMS announced a contract to upgrade a Gamma Knife to Perfexion specifications at Lehigh. As part of this upgrade, AMS agreed to the early termination of the existing 10-year lease on the Gamma Knife system it supplied to Lehigh in 2004, and Lehigh has agreed to purchase the Perfexion system. AMS expects pre-tax income of approximately $1 million from this transaction to be recognized in the third quarter of 2011.

Gross margin for this year's second quarter increased to 43.7% compared to 42.1% for the second quarter of 2010. Operating income increased 37.2% to $225,000 for the second quarter of 2011 compared to $164,000 for the second quarter of 2010.

Selling and administrative expenses for the second quarter of 2011 decreased 3.9% to $1,041,000 compared to $1,083,000 for the second quarter of 2010. Reflecting the addition of new Perfexion systems to AMS' Gamma Knife portfolio, interest expense increased to $570,000 for this year's second quarter compared to $503,000 for the second quarter last year.

Cash flow, as measured by earnings before interest, taxes, depreciation and amortization (EBITDA), was $2,034,000 for the second quarter and $4,081,000 for the first six months of 2011, compared to $2,001,000 for the second quarter and $3,985,000 for the first six months of 2010.

Balance Sheet Highlights

At June 30, 2011, AMS reported cash, cash equivalents and certificates of deposit of $9,818,000 compared to $10,438,000 at December 31, 2010. Shareholders' equity at June 30, 2011 was $23,954,000, or $5.19 per outstanding share. This compares to shareholders' equity at December 31, 2010 of $23,044,000, or $5.01 per outstanding share.

First Half Results

For the six months ended June 30, 2011, revenue increased 4.0% to $8,573,000 compared to $8,243,000 for the first six months of 2010. Operating income increased 40.5% to $451,000 for this year's first half compared to $321,000 for the first half of last year. Net income for the first six months of 2011 increased to $42,000, or $0.01 per diluted share, compared to net income for the first six months of 2010 of $11,000, or 0.00 per diluted share.

CEO Comments

Chairman and Chief Executive Officer Ernest A. Bates, M.D., said, "Higher Perfexion procedure volume, the result of our strategy to upgrade many of our existing Gamma Knife sites to Gamma Knife Perfexion specifications, contributed to the improvements in gross margin and operating income for the second quarter and first half of 2011 versus prior year. We continue to move this upgrade program forward. In June we announced that the Perfexion system AMS supplied to Lovelace Medical Center in Albuquerque, New Mexico began treating patients. This system is an upgrade to the Gamma Knife supplied by AMS to Lovelace Medical Center in 2003. Additional Perfexion contracts are in the pipeline.

"Also in the second quarter, the Gamma Knife system we supplied to Baskent University, Adana, Turkey under a contract announced in March 2011 began treating patients. The Kisla Campus of Baskent University houses the largest and most modern oncology center in the Adana region, now including both a Gamma Knife and two linear accelerator devices used for radiation therapy. Turkey is the fastest growing economy in Europe and the third fastest growing economy in the world behind only China and India. Given the small number of radiosurgery devices and services in the country today, and the fact that more than 90% of the population of 77 million is covered by health insurance, Turkey represents a significant growth opportunity for AMS. We also anticipate that our Gamma Knife unit at Hospital Central FAP in Lima, Peru will begin treating patients later this year, and our linear accelerator site in Sao Paulo, Brazil is scheduled to go on-line in 2012."

Dr. Bates said that the Company is negotiating financing for the four proton therapy centers AMS currently is developing in Dayton, Ohio, Boston, Massachusetts, Orlando, Florida, and Long Beach, California. "Proton therapy is widely regarded as the optimal radiation treatment for an increasing variety of cancers. With our many years of experience in radiation therapy equipment selection and innovative financing, American Shared is ideally positioned to take advantage of this growth opportunity," he said.

What is

GK? This is a singular diagnosis modality section that emits 201 Gamma Ray beams stereotactically as well as precisely to a brain lesion though deleterious surrounding tissue. It was invented by Professor Lars Leksell in 1968 during a Karolinska Institute, Stockholm, Sweden.

This is a great healing grant to humanity, as well as is right away during large famous as a most appropriate preference for a diagnosis of most brain diseases. This diagnosis requires a rarely learned as well as competent, together with doctors, nurses, healing physicists as well as technologists.

GK record itself is a vital breakthrough. It maximizes a correctness as well as capability regulating imaging techniques similar to CT, MRI as well as intelligent angiography that capacitate a medicine as well as healing physicist to precisely fix up a lesion as well as afterwards work out a volume as well as strength of deviation needed.

For treatment, a support stereo-tactic is practical to a accurate place of a lesion to be treated. When a event of a focus is complete, a horizon will progressively degenerated, as well as finish diagnosis procession is completed. The diagnosis itself customarily takes thirty mins to 2 hours. After execution of diagnosis procedures, a doctors during a sanatorium will comply a studious for a singular night prior to discharge.

AVM (Arterio Venous Malformations) and treatment through Gamma Knife Radio surgery

Arterio Venous Malformation more commonly known as AVM can be simply explained as the group of blood vessels that are abnormally connected to each other. Though AVM can be present in any part of the body, it is of much significance in brain as it can disrupt normal functioning of the brain and can even be fatal in some cases.

The malformation in the brain is such that the capillary bed (very thin blood vessels that connect arteries to the veins) is missing, thereby passing on the high blood pressure that arteries carry directly to the veins. The increase in pressure cause the AVM to enlarge with time and affect the surrounding brain tissues, which may lead to seizures, headaches, and stroke symptoms such as hemiplegia or hemiparesis. They can be found anywhere in the brain, brainstem, white matter or the cortex.

AVM is usually detected between the ages of 10 to 30, but sometimes go unnoticed till the age of 50 or even beyond. The patient does not know if he is suffering from AVM until it bursts leading to severe headache, stroke or seizure. The reason why AVMs develop is not known, but most of the patients are born with it- it is most commonly a congenital disorder.

Outcome predictors of Gamma Knife radiosurgery for renal cell carcinoma metastases - Abstract

Although whole brain radiation therapy (WBRT) has been a standard palliative management for brain metastases from renal cell carcinoma, its benefit has been elusive because of radiobiological resistance.

We evaluated the role of stereotactic radiosurgery (SRS) in the management of brain metastases from renal cell carcinoma.

We reviewed records from 158 consecutive patients (male=111, female=47) who underwent SRS for 531 brain metastases from renal cell carcinoma. The median patient age was 61 years (38-83 years) and the median number of tumors per patient was one (1-10). Seventy-nine patients (50%) had solitary brain metastasis. Fifty-seven patients (36%) underwent prior WBRT. The median total tumor volume for each patient was 3.0 cc (0.09-47 cc).
