This is a thin, flexible tube with a tiny camera and a light. An ear, nose, and throat doctor (otolaryngologist) will often do this procedure in his or her office. The sinuses are a group of spaces formed by the bones of your face. They connect with your nasal cavity. This is the air-filled space behind your nose. During the procedure, the healthcare provider inse...

  • Necrotizing Colitis

    Posted: 08/25/2016

    Necrotizing Colitis What is necrotizing colitis? Necrotizing colitis (NC) is a serious health problem. It happens when part of your colon dies. This is often because of colon cancer. If you have NC, it usually means you need to have emergency surgery. Your large intestine is part of your digestive (gastrointestinal or GI) tract. The GI tract goes from your mouth down to your rectal opening. The large intestine is made up of your colon and rectum. The colon receives food that’s broken down in your small ...

  • Necrotizing Pancreatitis

    Posted: 08/25/2016

    Necrotizing Pancreatitis What is necrotizing pancreatitis? Necrotizing pancreatitis (NP) is a health problem in which part of your pancreas dies. This is because of inflammation or injury. If the dead tissue gets infected, it can cause serious issues. The pancreas is an organ that sits behind your stomach. It makes fluids that flow through a duct into the small intestine. These fluids help you digest food. The pancreas also releases hormones to help control blood sugar. This includes insulin. Pancreatit...

  • Neuronal and Mixed Neuronal-Glial Tumors

    Posted: 08/25/2016

    Neuronal and Mixed Neuronal-Glial Tumors What are neuronal and mixed neuronal-glial tumors? Neuronal and mixed neuronal-glial tumors are a group of rare tumors that occur in the brain or spinal cord. Together, your brain and spinal cord make up your central nervous system (CNS). Many of these tumors are benign (noncancerous). Benign means that the growth does not spread to other parts of the body. However, these tumors can be dangerous because they can cause seizures or other problems by pressing agains...

  • Nasal Polyps

    Posted: 08/25/2016

    Nasal Polyps What are nasal polyps? Nasal polyps are abnormal, soft, swollen, sac-like growths of inflamed tissue. They line the inside of your nose or your sinuses. The sinuses are a group of air-filled spaces inside the bones of your face. They connect with the nasal cavity, the large, air-filled space behind your nose. Normally, these spaces are relatively open, but nasal polyps can grow to obstruct them. This can cause difficulty breathing. Nasal polyps are a subgroup of chronic rhinosinusitis. This...

  • Neurogenic Bowel

    Posted: 08/25/2016

    Neurogenic Bowel What is neurogenic bowel? Neurogenic bowel is the loss of normal bowel function. It’s caused by a nerve problem. A spinal cord injury or a nerve disease may damage the nerves that help control the lower part of the colon, which sends solid waste out of the body. This interferes with the normal ability to store and eliminate waste. It often causes constipation and bowel accidents. The food you eat goes to your gastrointestinal tract (GI tract) for digestion. You might think of your GI tr...

  • Normal Pressure Hydrocephalus

    Posted: 08/25/2016

    Normal Pressure Hydrocephalus What is normal pressure hydrocephalus? The brain has chambers called ventricles that normally contain fluid. This fluid is called cerebrospinal fluid (CSF). It cushions the brain and spinal cord. Normally your body makes just enough CSF each day and absorbs that same amount. Sometimes, however, too much fluid can build up in the ventricles. This can lead to a normal pressure hydrocephalus (NPH). What causes normal pressure hydrocephalus? The cause of excess fluid in the ven...

  • Neuromyelitis Optica

    Posted: 08/25/2016

    Neuromyelitis Optica What is neuromyelitis optica? Neuromyelitis optica, also called NMO or Devic's disease, is a rare yet severe demyelinating autoimmune inflammatory process affecting the central nervous system. It specifically affects the myelin, which is the insulation around the nerves. NMO mainly affects the spinal cord and the optic nerves -- the nerves that carry signals from the eyes to the brain. As a result, the disease can cause paralysis and blindness. Neuromyelitis optica most often strike...
