found in liver, whole milk, fortified food products, whole eggs, colorful fruits and vegetables (carrots, cantaloupes, sweet potatoes, spinach, etc.), and lots more. Vitamin A deficiency can
cause night blindness, blindness, infectious diseases, pneumonia, and others.
Vitamin B1 (thiamine) -- one of the B vitamins; helps the body convert carbohydrates into glucose, which is burned up to produce energy. B vitamins also help the body metabolize fats
and proteins. They are necessary for healthy hair, skin, eyes, and liver. They also help the nervous system function properly and are necessary for optimal brain function. All B vitamins are
water-soluble. Thiamine is considered an anti-stress vitamin because it may strengthen the immune system and improve the body's ability to withstand stressful conditions. It was the first B
vitamin discovered. Thiamine plays a crucial role in certain metabolic reactions. Symptoms of a thiamine deficiency are fatigue, irritability, depression, and abdominal discomfort. Thiamine is
used to treat beriberi. Thiamine is found in pork and organ meat, whole-grain or enriched cereals and rice, legumes, wheat germ, bran, brewer's yeast, and blackstrap molasses.
Vitamin B2 (riboflavin) -- one of the 8 B vitamins; helps the body convert carbohydrates into glucose, which is burned up to produce energy. B vitamins also help the body metabolize fats
and proteins. They are necessary for healthy hair, skin, eyes, and liver. They also help the nervous system function properly and are necessary for optimal brain function. All B vitamins are
water-soluble. Riboflavin acts as an antioxident by scavenging damaging particles in the body known as free radicals, which can damage cells and DNA, and contribute to aging and a
number of health conditions, such as heart disease and cancer. Riboflavin is needed to help the body convert vitamin B6 and folate into active forms. It is important for body growth and red
blood cell production. Symptoms of riboflavin deficiency are fatigue, slowed growth, digestive problems, cracks and sores around the corners of the mouth, swollen magenta tongue, eye
fatigue, swollen sore throat, and sensitivity to light. Riboflavin is found in brewer's yeast, almonds, organ meats, whole grains, wheat germ, wild rice, mushrooms, soybeans, milk, yogurt, eggs,
broccoli, Brussels sprouts, and spinach.
vitamin B3 (niacin) -- one of 8 B vitamins; helps the body convert carbohydrates into glucose, which is "burned" to produce energy. B vitamins also help the body metabolize fats and
protein. They are necessary for healthy skin, hair, eyes, and liver. They also help the nervous system function properly and are necessary for optimal brain function. Niacin helps the body
make various sex-related and stress-related hormones. It is effective in improving circulation and in reducing cholesterol levels in the blood. All B vitamins are water-soluble, so the body
does not store them. Vitamin B3 deficiency can cause indigestion, fatigue, canker sores, vomiting, depression, pellagra, and others. Vitamin B3 is found in beets, brewer's yeast, beef liver,
beef kidneys, fish, salmon, swordfish, tuna, sunflower seeds, and peanuts. Many foods are fortified with vitamin B3.
Vitamin B5 (pantothenic acid) -- one of the B vitamins; helps the body convert carbohydrates into glucose, which is burned up to produce energy. B vitamins also help the body
metabolize fats and proteins. They are necessary for healthy hair, skin, eyes, and liver. They also help the nervous system function properly and are necessary for optimal brain function. All
B vitamins are water-soluble. Vitamin B5 is important in the secretion of hormones, and possibly to help prevent wrinkles and graying hair. Symptoms of a vitamin B5 deficiency are fatigue,
headaches, nausea, tingling in the hands, depression, personality changes and cardiac instability. Vitamin B5 is found in beef, brewer's yeast, eggs, fresh vegetables, kidney, legumes, liver,
mushrooms, nuts, pork, saltwater fish, whole rye flour, and whole wheat.
Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine, or pyridoxine hydrochloride) -- one of the B vitamins; helps the body convert carbohydrates into glucose, which is burned up to
produce energy. B vitamins also help the body metabolize fats and proteins. They are necessary for healthy hair, skin, eyes, and liver. They also help the nervous system function properly
and are necessary for optimal brain function. All B vitamins are water-soluble. Vitamin B6 is essential for protein metabolism, red blood cell metabolism, the function of the nervous and
immune systems, and for the conversion of tryptophan to niacin. It also helps maintain blood sugar levels. A vitamin B6 deficiency can result in anemia. Vitamin B6 is found in fortified
cereals, beans, meat, poultry, fish, and some fruits and vegetables.
Vitamin B7 (biotin) -- one of the B vitamins; helps the body convert carbohydrates into glucose, which is burned up to produce energy. B vitamins also help the body metabolize fats and
proteins. They are necessary for healthy hair, skin, eyes, and liver. They also help the nervous system function properly and are necessary for optimal brain function. All B vitamins are water-
soluble. Biotin is necessary for cell growth, the production of fatty acids, the transfer of carbon dioxide, maintaining a steady blood sugar, strengthening hair and nails. Biotin is found in
egg yolk, liver, and some vegetables.
Vitamin B9 (folic acid) -- one of the B vitamins; helps the body convert carbohydrates into glucose, which is burned up to produce energy. B vitamins also help the body metabolize fats
and proteins. They are necessary for healthy hair, skin, eyes, and liver. They also help the nervous system function properly and are necessary for optimal brain function. All B vitamins are
water-soluble. Folic acid plays an important role in mental and emotional health. It aids in the production of DNA and RNA, and is important for rapid growth (infancy, adolescence,
pregnancy). It helps regulate the formation of red blood cells and helps iron function properly in the body. Folic acid deficiency can be caused by alcoholism, irritable bowel syndrome,
and celiac disease. Folic acid deficiency can cause poor growth, tongue inflammation, gingivitis, loss of appetite, shortness of breath, diarrhea, irritability, forgetfulness, and mental
sluggishness. A deficiency of folic acid in pregnancy is associated with low birth weight and an increased risk of neural tube defects, including cleft palate, spina bifida, and brain
damage. Folic acid can be found in spinach, dark leafy greens, asparagus, turnips, beets, mustard greens, Brussels sprouts, lima beans, soybeans, beef liver, brewer's yeast, root
vegetables, whole grains, wheat germ, bulgar wheat, kidney beans, white beans, mung beans, salmon, orange juice, avocado, and milk.
Vitamin B12 (various cobalamins) -- one of the B vitamins; helps the body convert carbohydrates into glucose, which is burned up to produce energy. B vitamins also help the body
metabolize fats and proteins. They are necessary for healthy hair, skin, eyes, and liver. They also help the nervous system function properly and are necessary for optimal brain function. All
B vitamins are water-soluble, however, Vitamin B12 can be stored for years in the liver. A deficiency of Vitamin B12 can cause anemia, numbness or tingling in the arms and legs, weakness,
and loss of balance. Vitamin B12 is found in eggs, meat, poultry, shellfish, milk, and milk products.
Vitamin D -- a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced by sunlight. Vitamin D is essential for
promoting calcium absorption in the gut, maintaining proper calcium levels in the blood, and bone growth. A deficiency of Vitamin D causes rickets and osteomalacia. Sources of Vitamin D
are sunlight, tuna, salmon, mackerel, and fish liver oils.
Vitamin E -- a fat-soluble vitamin found in many foods, fats, and oils. It is an antioxident. Vitamin E is important in the formation of red blood cells and helps the body use Vitamin K.
Symptoms of Vitamin E deficiency are muscle weakness, loss of muscle mass, abnormal eye movements, impaired vision, and unsteady gait. Vitamin E is found in liver, eggs, nuts, sunflower
seeds, corn-oil margarine, mayonnaise, dark green leafy vegetables, sweet potatoes, avocado, asparagus, and yams.

voice disturbances -- may occur for a variety of reasons. Any change in the shape or functioning of the vocal cords will cause a voice disturbance. The vocal cords sit above the trachea,
and air from the lungs cause them to vibrate, producing the sounds of one's voice. There are five categories of conditions that can interfere with vocal cord vibration: 1) structural changes of
the vocal cords, such as growths (polyps, cysts, papilloma, or granuloma) can distort the straight edges of the cords; 2) neurogenic voice disorders, caused by brain/nervous system
damage or malfunction, include vocal fold paralysis, vocal tremor, and spasmodic dysphonia which can interfere with normal vibrations. Neurological diseases such as myasthenia gravis,
multiple sclerosis, amyotrophic lateral sclerosis, and Parkinson's disease can paralyze the vocal cords; 3) diseases such as respiratory infections, allergies, and esophageal reflux
disorder can cause swelling of the vocal cords and prevent normal vibrations; 4) vocal abuse (excessive or loud talking, excessive caffeine or alcohol intake, lack of water consumption,
exposure to fumes, smoking, etc.) can cause swollen vocal cords or growths on the folds; and 5) idiopathic voice disorders (unknown origin).

Whipple's disease -- a rare bacterial infection primarily affecting the small intestine. It can also affect the heart, lungs, brain, joints, and eyes. Left untreated, it is fatal. It is caused by the
Tropheryma whipplei bacteria. Classic signs and symptoms of Whipple's disease are joint pain, chronic diarrhea, weight loss, abdominal pain and bloating, fever, fatigue, and anemia. Less
common are darkening of the skin, enlarged lymph nodes, chronic cough, chest pain, pericarditis, heart failure, vision problems, dementia, facial numbness, headache, muscle weakness
or twitching, difficulty walking, and memory problems.
whipworm infections -- an infection caused by the roundworm Trichocephalus trichiura. Children can become infected if they swallow soil contaminated with whipworm eggs. The eggs
hatch and stick to the wall of the large intestine. Symptoms are blood diarrhea, iron-deficiency anemia, fecal incontinence, and rectal prolapse.

white blood cells -- one of the cells the body makes to help fight infections. There are several types, but the most common are lymphocytes and neutrophils. Lymphocytes are made in
the spleen, lymph nodes, and thymus gland. They identify foreign substances from bacteria or viruses and produce antibodies to target them. Neutrophils are made in the bone
marrow and circulate in the bloodstream. They move out of the blood vessels into the infected tissue to attack the bacteria. The pus in an abscess is made up
largely of neutrophils. White blood cells are also called leukocytes.
white cane -- see Hoover cane or long cane. A tool that can be used for a person with visual impairments to achieve independence; also a symbol for
citizens who are blind in our society. Historically, the cane, staff, and stick have acted as traveling aids for people who were blind or visually impaired. James
Biggs of Bristol, England claimed to have invented the white cane in 1921. In 1931, Guilly d'Herbemont launched a scheme for a national white stick
movement for people in France who were blind. England soon followed. In the United States, the Lions Club International began a national program promoting
the use of white canes in 1931. Dr. Richard Hoover developed the "long cane". October 15 is White Cane Safety Day. A person who is both deaf and blind
carries a white cane with red stripes. See illustration.

word -- a series of letters. Each word has to have at least one vowel. Each syllable is made by blending the sounds of each component. Here are the
rules: 1. C followed by E, I, or Y usually has the soft sound of S (cyst). 2. G followed by E, I, or Y usually has the soft sound of J (gym). 3. Digraphs
count as one sound and one letter and are never separated (ch, sh, th, ph, wh). 4. When a syllable ends in a consonant and has only one vowel, that vowel is short (fat, bed). 5. When a
syllable ends in a silent E, that is a signal that the vowel in front of it is long (make, gene). 6. When a syllable has two vowels together, the first vowel is usually long and the second silent
(pain, eat) (Diphthongs don’t follow this rule). 7. When a syllable ends in any vowel and is the only vowel, that vowel is usually long (me, my). 8. When a vowel is followed by an R in the same
syllable, that vowel is R-controlled, not long nor short. See vowels. 9. Words can have prefixes or suffixes added, which modifies their meaning (use, usable).

and orchestrated by a team of caring professionals and paraprofessionals.
writing -- the representation of language in a textual medium through the use of a set of signs and symbols. Writing is part of literacy, along with reading, speaking, and listening. There are
five stages in the development of writing: 1) the use of straight or curved lines that only the writer can interpret, and even then, not for long; 2) the writing of letters in different combinations to
represent words; 3) the attempt to assign a sound value to these "letters"; 4) the combining of letters to represent sounds rather than the use of single letters to stand for syllables; and 5) the
use of invented spelling, gradually replaced by conventional.

X-linked inheritance -- a pattern of inheritance in which a recessive gene is carried on the X chromosome. Males are more likely to be affected.
X-linked dominant trait (XLD) -- A mode of inheritance in which a gene on the X chromosome is dominant. Females can be more frequently affected than males since they have two X
chromosomes that could potentially carry the abnormal gene, whereas a male has only one. The affected X is NEVER passed from father to son, but to affected daughters. If a son inherits
the disorder from his mother, it seems to be more severe or fatal.
X-linked recessive trait (XLR) - A trait transmitted by a gene located on the X chromosome. It is passed by a carrier mother to an affected son; or to a daughter, who is then also a carrier.
Alternately, if the gene is located on the (affected) father's X chromosome, it cannot be passed to his son but to a carrier daughter, unless the mother is also a carrier, and the daughter gets
her carrier X. This makes this daughter affected.
x-ray -- a form of electromagnetic radiation. An x-ray machine sends individual x-ray particles, called photons, that pass through the body. Then a computer
or special film is used to record the images that are created. Structures that are dense, like bones, will block most of the x-ray particles and will appear white.
Metal and contrast material (such as special dyes used to highlight areas of the body) will also appear white. Structures containing air will be black, and muscle,
fat, and fluid will appear as shades of gray. See Homer.

malformations have been described in some girls including gonadal dysgenesis (nonfunctional ovaries), dysmorphic facial appearance, atrophic or dysplastic (absent or shrunken)
kidneys, and vaginal and uterine malformations. XXXX syndrome is associated with a mildly unusual facial appearance, behavioral problems, and moderate intellectual disability. XXXXX
