Are you getting enough vitamin B12? Many people don’t, and that deficiency can cause some serious problems. Vitamin B12 does a lot of things for your body. It helps make your DNA and your red blood cells, for examples. Since your body doesn't make vitamin B12, you'll need to get it from animal-based foods or from supplements, and it needs to be consumed on a regular basis. Exactly how much you need and where you should get it from depends on things like your age, the diet you follow, your medical conditions, and in some cases what medications you take.

The objective of carotid endarterectomy (CEA) is to prevent strokes. In the United States, stroke is the third leading cause of death overall and the second leading cause of death for women.[1] Among patients suffering a stroke, 50-75% had carotid artery disease that would have been amenable to surgical treatment. Several prospective randomized trials have compared the safety and efficacy of CEA with those of medical therapy in symptomatic and asymptomatic patients. Data from these prospective trials have confirmed that CEA offers better protection from ipsilateral strokes than medical therapy alone in patients presenting with either symptomatic or asymptomatic carotid artery disease.

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.

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.

Central venous access is essential in providing quality medical care to many patients for whom intensive therapy is required. In many situations, a semipermanent tunneled central line is preferred (see Indications). An anterior approach to the internal jugular vein (IJV) is the best option in this situation because it offers the easiest route with a low risk of complications. In this procedure, a tunneled catheter is surgically inserted into a vein in the neck or chest and passed under the skin. Only the end of the catheter is brought through the skin; medicines and intravenous (IV) fluid can be administered through this catheter; other tasks, such as blood sampling, can also be performed. The fact that the catheter is passed under the skin helps secure the catheter, reduces the rate of infection, and permits free movement of the catheter port. The placement of a tunneled catheter should be carried out by practitioners with specific experience in the procedure.

Scleral fixated IOLs in case of inadequacy of capsular support and scleral sutured capsular tension rings when adequate zonular support is inavailable have been recently used in cataract surgery. In these techniques, polypropylene suture is used and the suture ends over the sclera after the knot ha...s been formed, may erode the conjunctiva and become exposed. Thus, the erosion may lead to the development of endophtalmitis. In order to prevent the aforementioned complication, scleral flaps, otologous cornea, duramater or fascia lata patches have been used to cover the knot and rotation of the knot into the tissues has been described.
