The main related macular degeneration affects the dark area the rest now shown here known as the macular of there are two types have AMD dry and wet there is also an advanced dry phone call geographic atrophy the dry is caused by the accumulation of debris called bruising which first built up in 19 usually both eyes can develop the disease the dry form of agerelated macular degeneration may turn into the more serious wet form characterized by the creation up many new blood vessels and bleeding in the macular degeneration.
Blood turned into nerve cells by Canadian researchers.
Canadian scientists have discovered a way to turn a simple blood sample from a man or woman into a variety of nerve cells, including those that are responsible for pain, numbness and other sensations. This technology will allow researchers to test potential drugs for treating pain using the nerve cells in a lab, all based on an individual patient's own genetic signature, says Mick Bhatia, who led the team of researchers at McMaster University in Hamilton. Now we can take easy to obtain blood samples and make the main cell types of neurological.
Systems the central nervous system and the peripheral nervous system in a dish that is specialized for each patient. According to Mick Bhatia, Nobody has ever done this with adult blood, ever Up until now, there has been no good way to get access to human neural cells to test or study. While researchers can buy certain kinds of rat neural cell lines, they don't consistently respond the way human neural cells do. The new technique involves extracting stem cells from blood ones that normally have the potential to become red blood cells or various kinds.
Of white blood cells involved in fighting off pathogens. The blood stem cells are converted over about a month into neural stem cells using a patented technique. Those cells can survive for several months in a petri dish. These neural stem cells are then manipulated in the lab to give rise to several types of nerve cells, including those that make up the peripheral nervous system throughout the arms, legs and the rest of the body. We can actually take a patient's blood sample, as routinely performed in a doctor's office,.
And with it we can produce one million sensory neurons. We can also make central nervous system cells. The researchers hope to discover new pain drugs that take aim only at the peripheral nerve system, while not affecting the brain and the rest of the central nervous system. You don't want to feel sleepy or unaware, you just want your pain to go away, says Bhatia. His lab hopes to further develop the bloodgenerated neural stem cells into motor and other kinds of neurons that could conceivably one day be transplanted into patients to restore healthy.

What is Stargardt Disease
In starguardt disease a defective protein and photoreceptors result in the accumulation of apply perfusion in retinal pigment epithelium are paying cells as photoreceptors are shared a link why population is composed of material that is very talking to our ping you sell the RP cells become engorged with this toxic material and overtime again to shrink and die sent our PE cells are important for the survival a photo receptors when are being cells are lost from two of the photoreceptors applied directly above I'm and this leads to blindness the if you were patient with Stargardt's disease.
And you were looking at my face if we were early in the disease course a in my face might appear quite blurry and my features me not be recognizable whereas the purple purse the right now would be perfectly OK in later courses disease where you actually losing a lot of cells in the macular region my face would be entirely black again performed parts the right now would be fine inorg to see my face patients would typically look slightly askew so that my face falls on parts and.
Cyst Removal Leads to Permanent Nerve Damage Cleveland Attorney Will Eadie Explains
Let me tell you about a brick lawyer who went in for surgery to have a cyst removed from his wrist and ended up having permanent nerve injury. And the doctor wouldn't take responsibility for that mistake. Hi. I'm Will Eadie. I'm an Ohio medical malpractice attorney. This brick lawyer went in for optional surgery. He had a cyst he'd had it for years. And it didn't bother him that much but he decided to go in and have an optional surgery. The surgeon went in found that it was a different kind of cyst than they thought it was. And.
Instead of stopping the surgery, instead of making sure that this person wanted the surgery to move forward, he decided to just remove it anyways. We used the medical records and a medical expert to show that surgeon should not have gone ahead with that surgery without higher magnification eyepieces or loops. He wasn't able to see the difference between the cyst and the nerves and he ended up cutting the nerves. But he wouldn't take responsibility for it. We had to file suit to help our client get compensation for an injury that never.
A part of the cervical spine or neck that is important is the uncovertebral joint and that is this little triangular outcropping of bone right here this point as we get older starts to enlarge and push against this point and that creates a spur the spur can live right in this area and of course that spur is right where the nerve root exits and therefore that spur can compress a nerve root and it's quite a common problem for patients with neck shoulder and arm pain these are actual cervical vertebra.
Dr. Francis Farhadis Care Philosophy
My name's Francis Farhadi and I'm a surgeon scientist in the Department of Neurological Surgery. And I I work at the OSU Comprehensive Spine Center. I specialize in treating patients that have spinal cord and peripheral nerve related problems, both traumatic and degenerative in nature. My initial interest actually stems from a basic science background. My first job was actually in a research lab as a as an assistant. And my interest was peaked in spinal spinal cord and and nerve regeneration really from from the beginning. This eventually tied into an interest in neurosurgery and the natural follow through with that was an.
Spine Surgeon Dr. Shellock Discusses Spondylosis at Texas Back Institute
Welcome to Doc Talk, your guide to back and neck health from the spine specialists at the Texas Back Institute. Hi, I'm Dr. Jessica Shellock and I'm an orthopedic spine surgeon with the Texas Back Institute. I'm going to talk to you about spondylosis. So, first off, what is spondylosis Essentially it refers to the degenerative changes of the spinal canal, and it can affect the intervertebral discs, the bones and ligaments, and even the joints in the back of the spine. Basically, it's osteoarthritis of the spine, in the same.
Way you can have arthritis of the hips, knees, or other main joints. There's often a hereditary component to this, and although normal wear and tear is a process of aging, the severity with which this can affect individuals varies greatly. Many people will report a family history of spine problems with the back or the neck. Spondylosis can affect the neck, which we call the cervical spine, the midback, the thoracic spine, and even the low back, the lumbar spine. Basically, the main presenting complaint is often neck or back pain, and.
In most cases this can be treated fairly well with oral antiinflammatory agents and a short course of physical therapy or chiropractic care. Most patients will have a substantial relief of their symptoms within a matter of weeks to months. Sometimes, when the intervertebral discs are affected, they start to flatten out, and in doing so they can actually cause pressure onto the nerves or the spinal cord. When this happens, and a nerve gets compressed, many people will have symptoms such as shooting, shocklike pains into the arms or legs, and.
