Glossary & acronyms
congenital brain abnormality in which the occipital horns - the posterior or rear portion of the lateral ventricles (cavities) of the brain -- are larger than normal because white matter in the posterior cerebrum has failed to develop or thicken. One of the brain malformations that often occurs with Chiari Malformation.
CIC - Clean Intermittent Catheterization (kleen in-ter-MIT-nt KATH-uh-tuhr-uh-zay-shuhn)

The right hemisphere controls the muscles on the left side of the body, and the left hemisphere controls the muscles on the right side of the body.
- Cerebrospinal Fluid [ser-eh-broh-SPY-nal FLOO-id]
- The fluid that flows in and around the hollow spaces of the brain and spinal cord, and between two of the meninges (the thin layers of tissue that cover and protect the brain and spinal cord). Cerebrospinal fluid is made by tissue called the choroid plexus in the ventricles (hollow spaces) in the brain. Also called CSF.
- Cerebrum [seh-REE-brum]
- The largest part of the brain. It is divided into two hemispheres, or halves, called the cerebral hemispheres. Areas within the cerebrum control muscle functions and also control speech, thought, emotions, reading, writing, and learning.
- Chiari Malformation - (key-AR-ee mal-for-MAY-shun)
- refers to the downward displacement of the 4th ventricle, brain stem and cerebellum, into the top of the spinal canal. First described in the 1890's by Dr. Hans Chiari. It is unknown why Chiari Malformation occurs with MMC. Possibly the best theory is the theory that assumes that “the primary problem is the lack of expressions of specific surface molecules (cellular adhesion molecules) on neurons developing neural tube”. Also referred to as Chiari Type II or Arnold Chiari Type II Malformation.

If there is no growth at the end of that time, the culture is considered negative for significant number of microorganisms that could cause an infection. If bacteria are present, the total number of organisms are counted and identified. In addition, antibiotics are identified that can be used to treat the infection.

solution. Developed by Dr. Peter G. Chait of the Hospital for Sick Children in Toronto, Canada.
