Rickets affects the structure of the growing bone, causing deformities of the skull, ribs and limbs. Bones that lack minerals are weak and, consequently, the weight of the body causes the bones of the legs to become bowed. Vitamin D deficiency has long been regarded as the main cause of rickets. Between 20-40% of infants and toddlers in countries located at high latitudes with long dark winters, and in more tropical regions when access to sunlight is limited, may be affected. Rates are now less than 1% in countries where vitamin D is given as supplements or added to infant formulae. However, cases of rickets are still observed in infants and toddlers, especially in breast-fed infants and in those receiving vegetal milk-substitutes, and in older children and adolescents. These children usually combine several risk factors including: heavy skin pigmentation, lack of sun exposure and low vitamin D intake. Cases of rickets have also been observed in children with severe calcium deficiency and in premature babies with phosphate deficiency. Some extremely rare cases of rickets are due to hereditary or acquired vitamin-D resistant rickets.

Radiology Resident Case of the Week: October 31, 1996 X-linked Hypophosphatemic Rickets Mark A. Nathan, M.D. Peer Review Status: Internally Peer Reviewed Clinical Sx: An infant male who underwent first radiologic evaluation for short stature at the age of 16 months. Etiology/Pathophysiology: The patient presented had a genetic form of hypophosphatemic rickets inherited in an X-linked dominant fashion. It is characterized by life-long hypophosphatemia. Several theories have been postulated for the cause of this syndrome. Original researchers believed that this represented a primary abnormality in calcium absorption from the gut with the depressed serum phosphate levels resulting from secondary hyperparathyroidism induced phosphaturia. However, most patients have normal serum PTH levels and no radiographic changes of secondary hyperPTH. The prevailing theory at present is that there are two mechanisms by which the kidneys resorb phosphate, a PTH sensitive mechanism accounting for two-thirds of the resorption and the other third being sensitive to serum calcium levels. It is believed that the hypophosphatemia in X-linked rickets is due to absence of response of the tubules of the kidney to PTH thus eliminating the PTH sensitive two-thirds of phosphate resorption. Pathology: As is common to all forms of rickets, the major abnormality is the lack of calcification of developing cartilage and bone due to insufficient availability of inorganic components of bone. This is primarily manifested in long bones as the lack of formation of the provisional zone of calcification.

Paediapaedia: Musculoskeletal Diseases Rickets Michael P. D'Alessandro, M.D. Peer Review Status: Internally Peer Reviewed Clinical Presentation: Not applicable Etiology/Pathophysiology: A metabolic bone disease characterized by a failure of normal mineralization of growing bone due to Vitamin D deficiency. Causes of Vitamin D deficiency include nutritional deficits (dietary or lack of sunlight), malabsorption (pancreatic insufficiency, hepatobiliary disease, small bowel disease), renal disease (renal glomerular or tubular disorders),and increased Vitamin D requirement (Vitamin D resistance, anticonvulsant therapy). Pathology: Not applicable Imaging Findings: On plain film there is characteristic flaring, cupping, expansion and irregularity of the metaphysis. This is because bone matrix or osteoid continues to form but cannot be calcified and the accumulation of this non calcified osteoid results in the irregular appearance of the metaphysis. In severe cases periosteal elevation can be seen. Expansion and fraying of the rib ends is called rachitic rosary. DDX: Not applicable References: See References Chapter.

ABC Home Radio Television News ... Podcasts Print Email to a friend Veils and dark skin risk rickets Wednesday, 5 September 2001 (Pic: Medical Journal of Australia) Pregnant women who have dark skin or wear veils are at high risk of vitamin D deficiency, which can lead to rickets in children, studies in Melbourne have found. Two studies reported in the Medical Journal of Australia this week found that a high proportion of dark-skinned and/or veiled women had vitamin D levels below the ideal. As well as problems such as rickets for the infants, a deficiency in adults can lead to bone-softening conditions such as osteomalacia and muscle disorders. "We are not suggesting people ignore health warnings to go out into the sun," said Dr Ruth Morley from the Royal Children's Hospital , co-author of one of the studies. "We would like people to take vitamin D supplements." Ninety per cent of vitamin D in the body is derived from the chemical reaction that occurs when ultraviolet B light hits the skin. Dark skin does not absorb as much ultraviolet B as light skin, and people who wear clothing that covers all their skin are not exposed at all to the sun. Dark-skinned or veiled women should visit their doctor, as vitamin D supplements from pharmacies would probably not be sufficient, Dr Morley recommended.

Rickets Q: What is rickets? A: Rickets is a disease caused by deficiency of Vitamin D leading to bony deformities and hypocalcemia. Q: Discuss pathophysiological basis of radiographic findings in Rickets. A : Loss of orderly maturation and mineralization of cartilage cells at the growth plate resulting from Vitamin D deficiency is ‘Rickets’. Thus, Rickets is like osteomalacia in a growing skeleton. The skeletal effects are due to lack of calcification of osteoid. The most obvious change are at ‘metaphysis’- where rapid growth is occurring. First change to appear is a ‘loss of normal zone of provisional calcification’ adjacent to metaphysis. This begins as an indistinctness of the metaphyseal margin, progressing to a ‘frayed’ appearance with widening of the growth plate, due to lack of calcification of metaphyseal bone. A similar but less marked effect occurs in subperiosteal layer , which may cause lack of distinctness of cortical margin.

Did Neanderthal Man have Rickets? Many people think that Neanderthal man was just a normal human who suffered from a disease. While there is no question as to the full humanity of the Neanderthals, their appearance is not due to disease. What follows is an excerpt from Dr. Cuozzo's book "Buried Alive - The Startling Truth about Neanderthal Man" Soon I will be posting an audio file that you can download and listen to from one of Dr. Cuozzo's radio interviews about rickets, and I will also post a shorter version of the text below. Buried Alive Chapter 16, Research Note 1. Is disease the cause of Neanderthal form? The Neanderthal facial and skeletal form have been attributed to pathological and nutritional phenomena for years. This represents an attempt to classify them as non-evolutionary features and put them on the "shelf," thereby closing the issue. There are three major categories of causation that have been referred to in the literature: arthritis deformans, syphilis, and rickets. Lubenow mentions in his book that J. Lawrence Angel of the Smithsonian Institution wrote about the bones of the pelvis and base of the skull being deformed by vitamin D deficiency, otherwise known as rickets, also by a protein deficiency.

RICKETS Rickets making comeback; kids not getting enough sunlight By ERIN MCCLAM The Associated Press ATLANTA Childhood rickets a bone-softening disease that had become so rare the U.S. government stopped keeping statistics on it is making a comeback, in part because some youngsters are not getting enough sunlight, health officials say. Rickets, a vitamin D deficiency that causes bones to soften and bend and often results in bow legs, was once a major health problem. ~ The addition of vitamin D to milk in the 1930s virtually eliminated the disease. But health officials said Thursday that health departments across the United States are seeing a resurgence. The government attributes the comeback to the popularity of milk substitutes like soy that lack certain nutrients (Vitamin D) ; the failure to supplement breast milk with vitamin D; and a lack of childhood exposure to sunlight. ~ Sunlight stimulates the body to produce vitamin D. The resurgence has been seen particularly among children breastfed by black mothers. Dark-skinned people absorb less sunlight.

Rickets, which can cause bone deformities and other health problems, is caused by a lack of vitamin D which prohibits the body from properly utilizing calcium. Primarily at risk for the disease are dark-skinned infants who are always heavily clothed or live where there is little sunshine. Babies of mothers who have low vitamin D stores may also be at risk. Research suggests that people of color, especially religious or cultural groups who wear enveloping clothing should expose their babies' uncovered cheeks to sunlight for just 20 minutes a day to get the needed vitamin D. In cases where this is not possible or the mother is not getting adequate vitamin D, doctors may prescribe a vitamin D supplement for the baby. According to La Leche League International, the world's recognized authority on breastfeeding, rickets has rarely been found in fully breastfed infants. This is true even in northern climates where there is less exposure to sunlight, which activates the formation of vitamin D. Research has shown that human milk contains adequate vitamin D for at least the first 6 months of life.

Scientific Anti-Vivisectionism Home HEART FAILURE LEPROSY MALARIA ... treatment continued... TREATMENT for RICKETS DIET and SUNLIGHT (vitamin D) The connexion between abundance of sunlight and an absence of rickets was made by Theodor Palm, an English medical missionary, in the 19th century, whilst in the East - but his epidemiological findings were ignored(1). Use of cod liver oil had been known in Northern Europe since the 18th century and had been given prominence in the treatment of rickets in 1861 by Trousseau, a physician in Paris, in his textbook on clinical medicine. The link between diet and rickets was made by Jean Baptiste Dumas, a French chemist, who, in 1871, published details of his observations made of starving infants during the time that Paris was under seige from the Prussians. Dumas described the disasterous consequences of feeding these infants on artificial milk, prepared by emulsifying fat in a saturated solution(2). In 1880, Nicholas Lunin, in his doctorate thesis cited his experiments with mice, maintained on artificial diets. Mice reciving sodium carbonate lived for 12 to 30 days, whilst those not given this, lived for 12 to 21 days. Lunin found that "artificial milk did not improve survival of the mice" - but with no mention of the results observed by Dumas in children fed on this diet. Lunin found the mice thrived on powdered milk. Twenty five years later, Prof C A Pekelharing of the University of Utrecht in the Netherlands, published a paper in Dutch in 1905, describing his experiments which showed that mice could be kept healthy on an artificial diet to which a small amount of whey had been added - he had been preceded by Dumas over 30 years earlier, who had used emulsified fat in solution in his clinical application(2).
