Neurosurgery is the surgical specialty that addresses disorders and diseases of the brain and nervous system, as well as the arteries of the neck. Neurosurgeons diagnose and treat brain tumors, stroke, brain aneurysms, traumatic brain injury, seizure disorders, spinal disorders and movement disorders. Some neurosurgeons specialize in specific areas of the nervous system such as the brain, spinal cord or peripheral nervous system, or specific areas such as pediatric neurology, seizure disorders, neuro-oncology or neurovascular disorders.

Advanced imaging techniques such as CT, MRI, PET and magnetoencephalography are essential tools for microsurgery that substantially enhance accuracy and result in better outcomes. Minimally invasive techniques such as endoscopic endonasal surgery and ventricular endoscopy reduce collateral damage and speed recovery. More recently, surgeons have begun to use functional MRI intraoperative as well.

Neurosurgical treatments for stroke entail removing blood clots caused by accidents or hypertension to restore blood flow to a blocked artery in the brain. When a patient can be treated immediately following medical equipment South Africa the onset of symptoms, a neurosurgeon will generally administer tissue plasminogen activator (tPA), a medication that dissolves blood clots non-surgically. For patients who are not eligible for treatment with tPA, neurosurgeons may opt to remove or break up the clot via image-guided catheterization processes.

Preventative neurosurgical procedures for strokes include carotid endarterectomy, in which fatty plaques are removed from the carotid arteries, enabling blood flow to the brain. In carotid stenting, tiny wire mesh tubes are placed in the carotid artery to hold the artery open and ensure adequate blood supply.

Arteriovenous malformations (AVM), potentially life-threatening connections between arteries and veins in the brain, may be treated using procedures that block blood flow through embolization or radiosurgery. Depending on their location, brain tumors may be surgically removed or treated via radiosurgery as well.

Ventriculo-peritoneal and ventriculo-atrial shunting are surgical treatments for hydrocephaly, a condition in which cerebrospinal fluid fails to drain properly from the brain, putting pressure on delicate structures.

Seizures that cannot be controlled with medication may be treated through surgical removal of the locus of the abnormal electrical activity within the brain. A recently developed procedure entails insertion of a vagal nerve stimulator in the patient's neck to control seizures.

Other conditions treated by neurosurgeons include spinal tumors, spinal disc herniation, traumatic injury of peripheral nerves and spinal stenosis.

DME suppliers face big changes next year.

Starting in April 2008, retailers and suppliers in 10 metropolitan

areas who sell certain durable medical equipment will have to become

accredited and enter a competitive bidding process, according to a final

rule issued by the Centers for Medicare and Medicaid Services.

Unlike other entities, physicians may opt out of competitive

bidding and accreditation, but they will still have to accept a single

payment for the durable medical equipment (DME) item instead of a fee

schedule-based payment, Acting CMS Administrator Leslie Norwalk said in

a briefing with reporters.

The new competitive biddin

Water Damage in Hospitals by Leo Nov

Most hospitals would think that their facilities are maintained well until a small leak turns into a torrential flow of water, causing significant damage. Unfortunately, sudden water intrusion in a hospital could lead to several unique dangers and consequences.

Physically, water can damage the structures of the hospital and may even require reconstruction. There is also a risk of damage to expensive medical equipment, hospital furniture, and paper documents. There is also the possibility of system failure related to technology, electrical power or communication systems.

When any system of the hospital is affected, there will certainly be a disruption to services and opera

The Cell Phone Will See You Now

Pagers have been as synonymous with the medical community as scrubs, stethoscopes and lab coats.

But cell phones -- their electronic cousins -- have historically been persona non grata with the hospital set.

Electromagnetic interference from cell phones and other transmitting communication devices was thought to affect the performance of medical equipment.

Now, as technology improves, more hospitals in the United States and the United Kingdom are relaxing and lifting long-standing bans on cell phones.

But though the door is unlocked, it's not swinging all the way open. Experts caution that though the interference risks are low, they are still significant enough to

Radiation protection and the safe use of X-ray equipment: laws, regulations and responsibilities.

Background. South Africa's regulatory framework for

electromagnetic medical devices has come under considerable criticism.

Here it is reviewed in terms of how it has given form to protective

measures against ionising radiation. The Hazardous Substances Act

provides for effective protection against radiation, but has been

undermined by poor administration and uncertainty about regulations and

licensing conditions. The legal weight of enforcing licensing conditions

through a website without proper consultation with all parties concerned

is questionable and ineffective. Effective and legal radiation control

is possible by activating

Single-Payer Advocates: It Hurts To Say I Told You So

The botched implementation of Obamacare has created a bittersweet moment for advocates of a universal, single-payer health care system: They saw this coming, but they can't gloat about it.

"We may have an 'I-told-you-so' moment, but it's hard to get any pleasure out of it knowing how many people are actually going to get hurt," said Stephanie Woolhandler, a New York-based doctor who co-founded Physicians for a National Health Program, a group that pushes for universal health care. "You had a bad system, and you're putting a patch on it using the same flawed insurance companies that got us here in the first place," she said.

In the seven weeks since the insurance exchanges creat
