Rickets is a childhood disorder where a vitamin D deficiency causes the softening and weakening of bones. Vitamin D allows the bones to absorb calcium and phosphorus from the gastrointestinal tract so when there is deficiency a child may experience delayed growth, muscle weakness or pain in the spine, pelvis and legs. Skeletal deformities can result from rickets which can cause bowed legs or knocked knees, thickened wrists and ankles or breastbone projection. (1)
The Office of Rare Diseases (ORD) lists rickets as a rare disease with less than 200,000 people in the United States being affected. (2) However, it is a major health problem in other countries in the world. (3) There are ways to treat and prevent rickets before it gets to a point

where surgery is required. There are two main sources for vitamin D for children.
The first is sunlight. Your skin produces vitamin D when exposed to the sun. The second is food. Certain foods like fish oils and egg yolk contain vitamin D. There are also some foods where vitamin D is added such as fruit juices and milk. (1) There are, however, many factors that can put a child at risk for developing rickets. (4)
Since rickets is most common in children, age is risk factor. A child has rapid growth between the ages of 6 and 36 months so their bones need vitamin D the most to help with development. Rickets can appear in adults as well but this is rare. Diet is another factor. Breast milk alone doesn’t provide enough vitamin D to prevent rickets in infants so there has to be compensation somewhere. It makes it more difficult if a child has an allergy to milk or has issues with digestion.
Children in certain areas of the world are at higher risk because of their geographic location and skin color. Since our bodies produce more vitamin D when exposed to sunlight, children in parts of the world where there is limited sunlight may have issues. Someone of African, Pacific Islander, and Middle Eastern decent are at a high risk because darker complexions do not react as strongly to sunlight as lighter complexions which results in decreased production of vitamin
D. There is a type of rickets that has a genetic link called hereditary rickets. This type of rickets prevents the kidneys from absorbing phosphate. (4) Phosphate is needed for bone and teeth formation and therefor causes some of the same deformities as non-hereditary rickets such as bowed legs and knocked knees.
Anthropologists and geographers have studied and overtime come to the conclusion that distribution of skin color is not random. Darker skin color has been found to typically come from near the equator and lighter skin colors are typically coming from closer to the north and south poles. Over the years, researchers have found that darker skin colors has protected the skin from having skin cancer. Recent studies have shown that “skin color is the product of natural selection acting to regulate the effects of the sun’s ultraviolet radiation on key nutrients crucial to the reproductive success” (169).
Her findings from this research was praised as she concluded that small supplementary feeding with fruits, milk and wheat germ improved the growth of school children. She also found out that the over dosage of Vitamin D produced brittle bones and calcification of soft tissues. If that wasn’t enough, she continued her extensive research and showed that pantothenic acid is essential for normal pigmentation of hair and skin. Lastly she was intelligent enough to prove that the bone density of woman decreased between 50 and 65 years of
Physiological Basis of disease: DMD is the commonest and most serious form of the dystrophies. The gene responsible for dystrophin which, when absent, causes DMD. Amount of dystrophin correlates with the severity of the disease (i.e., the less dystrophin present, the more severe the phenotype). Since the gene is on the X chromosome, it primarily affects males, and females who are carriers have milder symptoms ( www.nlm.nih.gov/medlineplus/ency/article/000705.htm).

These include diseases such as rickets which is caused by a lack of vitamin D. A lack of calcium leads to poor growth in children. At this tender life stage this is a very negative thing because children are still at the peak of their physical development. The malnutrition could have caused stunting which is because the malnutrition hinders growth in their height and weight. Sometimes stunted growth can be permanent and a child may never be able to return to a normal height or weight.
Muscular Dystrophy is a genetic disorder in which your muscles drastically weaken over time. Muscles are replaced with “connective tissue,” which is more of a fatty tissue than a muscular one. The connective tissue is the tissue that is commonly found in scars, and that same tissue is incapable of movement. Although Muscular Dystrophy affects muscles in general, other types affect certain groups of muscles, and happen at different periods throughout a lifetime. For example one of the most common types, Duchenne Muscular Dystrophy, targets muscles in the upper thigh and pelvis. The disease is displayed throughout early childhood, usually between ages four and seven. This genetic disorder occurs only in boys. People have difficulty sitting up or standing and lose their ability to walk in their early teens. Sadly most people die by the age of twenty. A second common type, Becker’s Muscular Dystrophy affects the same muscles as Duchenne, but first appears in teenage years. Most people with Becker’s only live into their forties (Fallon 1824-1825).
Arthritis mainly affects people who are 18 and older, but kids are still able to get certain types of arthritis such as: Juvenile Rheumatoid Arthritis (JRA)
The major environmental risk factor for melanoma is overexposure to ultraviolet (UV) radiation from the sun. People who have fair skin that burns or freckles easily need to be especially careful in the sun as protecting yourself against UV overexposure is an important way you can help reduce your risk of developing melanoma.
It is estimated that 1 out of every 5,600-7,700 boys ages 5-24 have Duchene or Becker muscular dystrophy. (“Data & Statistics,” 2012 April 6) Muscular dystrophy is a group of genetic diseases defined by muscle fibers that are unusually susceptible to damage. There are several different types of muscular dystrophy some of which shorten the affected person’s lifespan. (“Muscular dystrophy: Types and Causes of each form,” n.d.) There is a long history of the disorder but until recently there wasn’t much knowledge of the cause. (“Muscular Dystrophy: Hope through Research,” 16 April 2014) Symptoms are obvious and can be seen as soon as a child starts walking. (“Muscular Dystrophy,” 2012 January 19) Although muscular dystrophy mostly affects boys, girls can get it too. (“Muscular Dystrophy,” 2012 January 19) There is no cure for muscular dystrophy but there are several types of therapy and most types of muscular dystrophy are still fatal. (“Muscular Dystrophy: Hope through Research,” 16 April 2014)
Osteogenesis imperfecta (OI), also known as brittle bone disease, is a rare genetic disorder with the main characteristic being that the bones break very easily, usually for no apparent reason. The major cause of osteogenesis imperfecta is a mutation in the genes that produce collagen. Collagen is the main protein that works toward the production of connective tissue. Individuals with this disorder will produce less collagen than needed, which causes the bone development to be endangered. This could result in bone deformities. There are four types of osteogenesis imperfecta, and in all four types you will see bone fragility with multiple fractures and bone deformities.
The syndrome is caused because of Genetic mutation that replaces connective tissues (muscles) with bones when someone gets injured instead of getting cured. This results in a new skeletal structure. Unfortunately this syndrome does not have any cure and the patients are advised to always be careful and not to fall or have any kind of traumas. They can’t engage in any sports in order to prevent any injuries. Surgery for removal of extra bones is not an option because removal of bones will lead to ingrowth of more bones. From previous cases it is seen that most of the patients suffering from this condition do not live more than 40 years and they die of respiratory
Since ancient times vitamin D has been the predominant cause of bone deficiencies.1 However, it was not in till the seventeenth century when both Dr. Daniel Whistler and Professor Francis Glisson made the first scientific description of a vitamin D deficiency.2 During the mid-seventeenth century there was an increase amount of children that were diagnosed with the bone disease called rickets.2 The cause of the rickets was determined to be associated to the lack of sunlight. A German researcher Kurt Huldschinsky came to the conclusion that when infants were exposed to ultraviolet light rays they became cured of rickets2. He stated that a substance in the skin was the potential source of the cure.2 In 1922, American scientist Elmer McCollum proved that when cod liver oil was heated; the beneficial effects of vitamin A in the oil were reduced.2 However, the oil remained effective in curing rickets leading McCollum to reason that a nutrient different from vitamin A was present in the oil. As a result, he named this nutrient vitamin D, which became the fourth vitamin to be discovered and named.2 Additionally, shortly after 1918, vitamin D was also discovered by an accidental experiment that included a group of scientists curing dogs affected with rickets by feeding cod liver oil to them.1
The body can manufacture only vitamin D; all others must be derived from the diet. Lack of them causes a wide range of metabolic and other dysfunctions. In the U.S., since 1940, the Food and Nutrition Board of the National Research Council has published recommended dietary allowances (RDA) for vitamins, minerals, and other nutrients.
Other metabolic bone diseases are osteoporosis, gout, OSTEOARTHRITIS, and PAGET'S DISEASE. Nutritional Disorders Nutritional deficiencies that result in bone damage include RICKETS in children and osteomalacia in adults, caused by a lack of vitamin D. In children, calcium and phosphate are poorly distributed on bones during development, resulting especially in deformity of the legs and arms. In adults, bones of the spine, pelvis, and legs become demineralized and the bones weaken.
My average intake is 66 mg. it is lower than the required Vitamin C intake. Deficiency in Vitamin C can develop scurvy, if vitamin C is missing on our diet. Oranges, lemon and other citrus fruits, bell pepper, kiwi broccoli, berries, tomatoes and papayas are rich in Vitamin C . Lack of Vitamin D on diet can develop rickets to small children. The required intake for this vitamins is 15microgram and my report is zero. Vitamin D can be achieved from exposure of skin to ultra violet rays of the sun. Vitamin E is responsible for transmission of nerve impulses, body weakness and eye problem that can cause blindness. My nutrient intake for Vitamin 10 mg AT and the require intake is 15 mg AT, which is 5 mg lower than the require amount. Food related to Vitamin E are green leafy vegies such as spinach, kale are rich in Vitamin E, in addition, broccoli, hazel nuts, squash and pumpkin are also rich in Vitamin E. My vitamin K intake is 3 microgram, way too low compared to the requirement which is 90 microgram. Vitamin K deficiency can cause hemorrhagic disease of new born. Food that gives Vitamin K are green leafy vegetables such as kale and spinach, canola oils, olive oils, and
