Causes
Cranial mononeuropathy III - diabetic type is a mononeuropathy, which means that only one nerve is damaged. It affects the third cranial (oculomotor) nerve, whi...

Cranial mononeuropathy VI
Cranial mononeuropathy VI is a nerve disorder. It prevents some of the muscles that control eye movements from working well. As a result, people may see two of the same image (double vision).
Causes
Cranial mononeuropathy VI is damage to the sixth cranial (skull) nerve. This nerve, also called the ...

Cranial sutures
Cranial sutures are fibrous bands of tissue that connect the bones of the skull.
Information
An infant's skull is made up of six separate cranial bones (the frontal bone, the occipital bone, two parietal bones, and two temporal bones). These bones are held together by strong, fibrous, elastic tissu...

Craniopharyngioma
A craniopharyngioma is a benign tumor that develops near the pituitary gland (a small endocrine gland at the base of the brain).
Causes
This tumor most commonly affects children between 5 and 10 years of age; however, adults can sometimes be affected. Boys and girls are equally likely to develop th...

Craniosynostosis
Craniosynostosis is a congenital (present at birth) defect that causes one or more sutures on a baby's head to close earlier than normal. Sutures are connections that separate each individual skull bones. The early closing of a suture leads to an abnormally shaped head.
Causes
The cause of craniosy...

Craniosynostosis repair
Craniosynostosis repair is surgery to fix damage caused by a birth defect that makes the bones in a child’s skull grow together too early.
Description
A baby's head, or skull, is made up of many different bones. The connections between these bones are called sutures. When a baby is born, it...

Craniosynostosis repair - discharge
Your child was in the hospital to have the connections between bones in their skull repaired. These connections are called sutures. When a baby is born, it is normal for these sutures to be open a little. This gives the baby’s brain and head room to grow.
Your baby was born with craniosynosto...

Craniotabes
Craniotabes is a softening of the skull bones.
Causes
Craniotabes can be a normal finding in infants, especially premature infants. Studies suggest it occurs in up to one third of all newborn infants.
Craniotabes is a harmless finding in the newborn, unless it is associated with other problems, suc...

Creatine phosphokinase test
Creatine phosphokinase (CPK) is an enzyme found mainly in the heart, brain, and skeletal muscle. This article discusses the test to measure the amount of CPK in the blood.

How the Test is Performed
Blood is typically drawn from a vein, usually from the inside of the elbow ...

Creatinine - blood
Creatinine is a breakdown product of creatine, which is an important part of muscle. This article discusses the laboratory test to measure the amount of creatinine in the blood.
Creatinine can also be measured with a urine test. See: Creatinine - urine

Creatinine - urine
Creatinine is a breakdown product of creatine, which is an important part of muscle. Creatinine is removed from the body entirely by the kidneys. This article discusses the test done to measure the amount of creatinine in your urine.
A blood test can also be used to determine your creatinine level. ...
-
Creatinine clearance
The creatinine clearance test compares the level of creatinine in urine with the creatinine level in the blood. (Creatinine is a breakdown product of creatine, which is an important part of muscle.) The test helps provide information on kidney function.

Creeping eruption
A creeping eruption is infection with dog or cat hookworm larvae.
Causes
Hookworm eggs are found in the stool of infected dogs and cats. When the eggs hatch, the resulting larvae infest the soil and vegetation. When you touch this infested soil, the larvae can dig into your skin, causing an intense...

Creutzfeldt-Jakob disease
Creutzfeldt-Jakob disease (CJD) is a form of brain damage that leads to a rapid decrease of mental function and movement.
Causes
CJD is believed to result from a protein called a prion. A prion causes normal proteins to fold abnormally. This affects the other proteins' ability to function.
There ar...

Crigler-Najjar syndrome
Crigler-Najjar syndrome is a very rare inherited disorder in which bilirubin (a substance made by the liver) cannot be broken down.
Causes
Crigler-Najjar syndrome is caused by an abnormal gene. The gene fails to make the enzyme that normally converts bilirubin into a form that can easily be removed...
