2010-03-16 DNA Test: Autism Genetic Test Doesnt Answer Most Parents Questions - On Parenting ( )

Right now, children suspected of having autism are tested for genetic abnormalities with two tests: the G-banded karyotype, which looks for abnormalities in the chromosomes, and fragile X testing, which looks for a specific variation on the X chromosome. Those two tests find genetic abnormalities in up to 5 percent of children with autism. In the new study, researchers used a newer test, chromosomal microarray analysis, to identify variations in much smaller chunks of DNA. That test turned up genetic abnormalities in about 7 percent of people with autism spectrum disorders, compared with about 2 percent of people tested with the karyotype method. The researchers, affiliated with institutions that are part of the Autism Consortium of Boston, point to that 5 percentage point difference and argue that the newer genetic test should be

2010-03-16 Allergy Tests: Statement of Anthony S. Fauci, M. D. , Director, National Institute of Allergy and Infectious Diseases, National Institutes of Health, on National Native HIV/AIDS Awareness Day , March

We as a nation must remove barriers to health care and routine HIV testing in native communities - and indeed, in all American communities - to improve the chances that individuals are diagnosed early in the course of HIV infection, when antiretroviral drugs can do the most good and opportunities for HIV prevention are greatest. Improved access to health care also would facilitate testing and treatment for other sexually transmitted infections, which place a burden on native communities and increase the risk of acquiring and spreading HIV.

2010-03-16 Body Fat Test: One way to figure out if you have osteoporosis is to have a DEXA scan and raquo; Standard-Times

A DEXA scan is a procedure that measures the amount of bone, muscle and/or body fat. DEXA stands for Dual Energy X-Ray Absorptiometry (or Densitometry). The DEXA determination of bone density or body composition is performed with an instrument that uses low energy x-rays.

For bone density measurements, scans are typically performed of the lumbar, the lower hip and the wrist. This is a common procedure for the diagnosis of osteoporosis and other bone diseases. For body composition measurements, a scan of the entire body is performed. A dexa scan is recommend for any woman 65 years or older, men that are 70 years or older, anyone being treated for osteoporosis or those taking a long term steroid that can thin their bones. The scan usually only takes about 10 minutes and uses very minimal radiation.

2010-03-16 Hepatitis B-HBV Test: Dynavax and Merck Agree on Final Reimbursements - MarketWatch

Currently available hepatitis B vaccines require three doses over six months to achieve full immunogenicity in healthy patient populations. Because compliance with this vaccine regimen is low, new vaccines are needed to provide increased protection in a shorter timeframe. Furthermore, currently available vaccines do not fully address the needs of several patient populations, including those with chronic kidney disease, HIV or chronic liver disease. In particular, patients with comprised immune systems require both rapid and enhanced protection, either because they are less responsive to conventional vaccine regimens or because they are at high risk of infection.

2010-03-16 Blood Grouping Test: Our Parents, Ourselves: Guidelines for prostate cancer tests

Officials said they felt that an update was needed in response to the recent findings of a large study involving 76,600 men in the United States who received annual PSA blood tests and digital rectal exams compared to those who had usual care.

ACS officials also want men to be aware of the uncertainty of tests results before making irreversible life-altering decisions. According to the ACS: No screening test is perfect, but the degree of over-diagnosis and associated over-treatment appears to be greater for prostate screening than for any other of the cancers for which routine screening currently occurs.

2010-03-16 Human Papilloma Virus HPV: Inaccurate reporting of scientific evidence perpetuates myths Guest Work

With large numbers of people vaccinated there will always be coincidental (and adverse) events occurring at the same time as an immunisation visit. Careful scientific review and use of large international databases and studies are used to determine whether rare events may or may not be linked to vaccines. The NZ safety surveillance system is one part of a broad international monitoring system for vaccine safety. The HPV Immunisation programme will have significant benefits for our communitys health Australia has already experienced a dramatic reduction in genital warts after only three years of HPV vaccination.

2010-03-16 Inflammatory Bowel Test: Genes Involved in Ulcerative Colitis Identified - insciences

Chronic inflammatory diseases (CIDs) comprise a class of disorders characterized by severe immune dysregulation and inflammation of otherwise healthy tissue. CIDs have a significant socio-economic impact, and affect up to 10 percent of the population in industrialized societies. It is known that many CIDs have a considerable genetic predisposition, including the Inflammatory Bowel Diseases (IBD). Crohns disease (CD) and Ulcerative Colitis (UC), the two major forms of IBD, manifest as chronic inflammation of the gastrointestinal tract, and recent data indicate that the gut microbiota may contribute to the perpetuation of the inflammatory process in genetically susceptible individuals.

2010-03-16 Cocaine drug Test: Police waited 2 months to investigate lab tech

The lab technician, Deborah Madden, 60, has not been charged with a crime associated with any theft of evidence at the lab, where she worked for 29 years until she retired Dec. 8. But suspicions that she stole and used cocaine - and her accusations that others in the lab were "sloppy" in their work - prompted police to shut down the drug lab Tuesday.

According to law enforcement officials with knowledge of the case, Maddens sister found cocaine in what appeared to be a lab vial at Maddens San Mateo home in December. Madden was away in an alcohol rehabilitation program at the time, said the officials, who spoke on condition of anonymity because the criminal investigation is continuing.
