• Saccade Initiation Failure, Congenital

What is Ocular Motor Apraxia, Cogan Type?
Cogan Type Ocular Motor Apraxia is a rare congenital disorder characterized by a defect in side-to-side eye movements. The eyes do not move properly in response to stimuli or voluntarily. When affected infants are asked to fixate on an object to the side, their eyes will lag and then move in the opposite direction. In order to compensate for this, the infants will sharply jerk their heads past the desired object in an effort to bring the eyes to a position where they can view the object. When the eyes fixate on the object, the head will return to its normal position. Before these head jerkings occur, an infant’s inability to fixate on an object may sometimes be mistaken for blindness.

What is Optic Neuritis?
Optic Neuritis is an inflammation that damages the optic nerve, a bundle of nerve fibers that transmits visual information from the eye to the brain. Pain and temporary vision loss in one eye are common symptoms of Optic Neuritis. Optic Neuritis is linked to Multiple Sclerosis (MS), a disease that causes inflammation and damage to nerves in the brain and spinal cord. Signs and symptoms of Optic Neuritis can be the first indication of Multiple Sclerosis, or they can occur later in the course of MS. Besides MS, Optic Neuritis can occur with other infections or immune diseases, such as Lupus.

Awareness Ribbon Color:

Red and White Pinstripes Ribbon for Oral Cancer, Lip and Oral Cavity Cancer and Oropharyngeal Cancer

What is Oral Cancer, Lip and Oral Cavity Cancer and Oropharyngeal Cancer (Head and Neck Cancer)?
The risk of Oral and Oropharyngeal Cancer is greatly increased by two factors:
• Tobacco use. Using tobacco, including cigarettes, cigars, pipes, chewing tobacco, and snuff, is the single largest risk factor for head and neck cancer. Eighty-five percent of Head and Neck Cancer is linked to tobacco use. Pipe smoking in particular has been linked to cancer in the part of the lips that touch the pipe stem. Chewing tobacco or snuff is associated with a fifty percent increase in the risk of developing cancer in the cheeks, gums, and inner surface of the lips, where the tobacco has the most contact. Secondhand smoke may also increase a person’s risk of Head and Neck Cancer.
• Alcohol. Frequent and heavy consumption of alcohol increases the risk of Head and Neck Cancer. Using alcohol and tobacco together increases this risk even more.

OTC is one of six enzymes that play a role in the break down and removal of nitrogen the body, a process known as the urea cycle. The lack of the OTC enzyme results in excessive accumulation of nitrogen, in the form of ammonia, in the blood. Excess ammonia, which is a neurotoxin, travels to the central nervous system through the blood, resulting in the symptoms and physical findings associated with OTC deficiency.

This leads to accumulation of bone with defective architecture, making them brittle and susceptible to fracture. In some cases, this is also accompanied by skeletal abnormalities. Although symptoms may not initially be apparent in people with mild forms of this disorder, trivial injuries may cause bone fractures due to bone fragility.

What is Ovarian Cancer, Childhood?
Childhood Ovarian Cancer is a rare type of cancer that occurs due to abnormal and uncontrolled cell growth in the ovaries. The childhood form, specifically, is extremely rare and accounts for less than five percent of all ovarian cancer cases. The most common types of Ovarian Cancers diagnosed in children and adolescents include Germ Cell Tumors, followed by Epithelial Tumors, Stromal Tumors, and then Other Tumors (such as Burkitt Lymphoma and Small Cell Carcinoma of the Ovary). Many people with early Ovarian Cancer have no signs or symptoms of the condition. When present, symptoms may include painful menstrual periods; an abdominal lump; pain or swelling in the abdomen; having male sex traits; and/or early signs of puberty. The underlying cause of childhood ovarian cancer is often unknown. Certain inherited conditions, such as Ollier Disease, Maffucci Syndrome and Peutz-Jeghers Syndrome are associated with an increased risk of developing Childhood Ovarian Cancer.
