(PhysOrg.com) -- A new study, aimed at estimating the prevalence of Down Syndrome in newborns, children and teenagers in 10 areas of the U.S., has found an increase in prevalence of more than 30 percent over the last 24 years. http://www.physorg.com/news178953188.html Medicine & Health Wed, 02 Dec 2009 07:20:02 EST news178953188 The addition of a "genetic sonogram" maximizes the accuracy of non-invasive testing for Down syndrome, said a Baylor College of Medicine researcher who was lead author of a landmark study in the current issue of Obstetrics and Gynecology. http://www.physorg.com/news177960758.html Medicine & Health Fri, 20 Nov 2009 18:00:04 EST news177960758 At birth, children with Down syndrome aren't developmentally delayed. But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development. http://www.physorg.com/news177777639.html Medicine & Health Wed, 18 Nov 2009 14:41:41 EST news177777639 New prenatal tests for Down syndrome are soon to be offered to all pregnant women across the United States, yet telling an expectant couple that their child will be born with Down syndrome is a task very few physicians are trained for, claims research published in the American Journal of Medical Genetics. The study, which reviewed decades of surveys and interviews, offers several recommendations for how physicians can best deliver the news. http://www.physorg.com/news173349204.html Medicine & Health Mon, 28 Sep 2009 09:38:57 EST news173349204 Matt Ziesel doesn't stray far from coach Dan McCamy on the sidelines during St. Joseph Benton High School's freshman football games. He likes to stay within earshot. http://www.physorg.com/news172676449.html Medicine & Health Sun, 20 Sep 2009 22:40:02 EST news172676449 An individual with Down syndrome and a male calico cat have one thing in common -- each has an extra chromosome. For animals, most instances of an extra chromosome result in birth defects or even death, but plants are another matter entirely. Many plants are able to survive the presence of an extra copy of their entire genome (known as polyploidy) and are often even more vigorous as a result. For plants, the process of polyploidy often results in a new species, making it an important mechanism in evolution. In fact, over 80% of plants may be a product of polyploidy. http://www.physorg.com/news172162573.html Biology Mon, 14 Sep 2009 16:10:02 EST news172162573 With new prenatal tests for Down syndrome on the horizon promising to be safer, more accurate, and available to women earlier in pregnancy, the medical community must come together and engage in dialogue about the impact of existing and expected tests, argues a new leading article published Online First by Archives of Disease in Childhood. http://www.physorg.com/news172146115.html Medicine & Health Mon, 14 Sep 2009 11:40:01 EST news172146115 For a decade now, the call has gone out every year on the ninth day of the ninth month warning women about the dangers of drinking while pregnant, yet Fetal Alcohol Syndrome remains stubbornly below the national radar, some health officials say. http://www.physorg.com/news171826511.html Medicine & Health Thu, 10 Sep 2009 20:10:01 EST news171826511 A study in the Aug. 15 issue of the Journal of Clinical Sleep Medicine shows that adults with Down syndrome also frequently suffer from obstructive sleep apnea (OSA). However, complications of untreated OSA such as cardiovascular disease, daytime sleepiness and impaired cognitive functioning overlap with the manifestations of Down syndrome; therefore, OSA may not be detected. http://www.physorg.com/news169537069.html Medicine & Health Sat, 15 Aug 2009 07:00:03 EST news169537069 Each year, approximately 4,500 children in America are diagnosed with leukemia, according to the Leukemia and Lymphoma Society. A potentially deadly cancer of the blood, it is the most common cancer in children. http://www.physorg.com/news168013026.html Medicine & Health Tue, 28 Jul 2009 15:17:47 EST news168013026 Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it's been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes. The late cancer researcher Judah Folkman, MD, founder of the Vascular Biology Program at Children's Hospital Boston, popularized the notion that they might be benefiting from a gene that blocks angiogenesis, the development of blood vessels essential for cancer's growth, since their incidence of other angiogenesis-related diseases like macular degeneration is also lower. A study from Children's confirms this idea in mice and human cells and identifies specific new therapeutic targets for treating cancer. http://www.physorg.com/news162043998.html Medicine & Health Wed, 20 May 2009 13:14:02 EST news162043998 Researchers at The University of Arizona are developing a set of standardized tests that could improve the lives of people with Down syndrome. http://www.physorg.com/news150991781.html Medicine & Health Mon, 12 Jan 2009 14:09:41 EST news150991781
