Osteomalacia (pronounced ), known as rickets in children, where the epiphyseal growth plates are yet to seal (taken from the Greek word (rhákis), meaning "spine"), is a disorder most commonly caused by vitamin D deficiency. This results in insufficient calcium uptake by bones in developing children. It can also arise, however, from other etiologies such as rare mesenchymaltumors or any phosphate-wasting disease. Because calcium is an essential nutrient which aids in bone rigidity, the lack of it being absorbed into the body causes fragile or malformed bones, which are unable to support the weight of a growing body. Calcium or phosphorus deficiency in children is termed rickets, while that of adults is termed osteomalacia.
Although osteomalacia can occur in adults, the majority of cases occur in children with poor nutrient intake usually resulting from famine or starvation during early stages of childhood.
Manifestations of disease
Rickets causes bone pain, slowed growth in children, dental problems, muscle loss and increased risk of fractures (easily broken bones). Medical problems seen in children with rickets are

NIH Scientists Identify Link Between Brain Systems Implicated in Schizophrenia Mon, 06 Oct 2008 11:30:00 -0400 Scientists at the National Institutes of Health have deciphered the complex relationship between three distinct brain circuits implicated in schizophrenia. The researchers determined that one brain circuit acts through an intermediary brain circuit. The intermediary circuit acts like a volume control knob, turning up the electrical activity of still another brain circuit, or turning it down. The finding suggests that schizophrenia could result from a malfunction anywhere in the link between these three brain circuits. NIH Launches New Web Site for Parents on Medical Research Studies for Children Mon, 06 Oct 2008 09:30:00 -0400 A new Web site from the National Institutes of Health (NIH), "Children and Clinical Studies" (www.ChildrenAndClinicalStudies.nhlbi.nih.gov), offers parents and health care providers an insider's guide to children's medical research. Scientists Identify Gene Variant Involved in Isolated Cleft Lip Mon, 06 Oct 2008 09:30:00 -0400 About 20 percent of isolated cleft lip, one of the world’s most common birth defects, may be due to a one-letter difference in the DNA sequence of a gene involved in facial development, researchers supported by the National Institutes of Health report.
