Diagnosis is the act or process of identifying or determining the nature and cause of a disease or injury through evaluation of patient history, examination, and review of laboratory data.
Vitamins C and E and beta carotene again fail to reduce cancer risk in randomized controlled trial – Women who took beta carotene or vitamin C or E or a combination of the supplements had a similar risk of cancer as women who did not take the supplements, according to data from a randomized controlled trial in the December 30 online issue of the Journal of the National Cancer Institute.
Early and accurate diagnosis of pediatric weight issues is an essential first step in identifying the obesity problem. – Despite recent widespread media attention given to studies that have indicated one-third of American children have a weight problem, a new study shows just one-third of children who are overweight or obese actually receive that diagnosis by a pediatrician.
Cell phones using lens-free imaging promise to improve health monitoring; New advances result in accurate ID of smaller particles using holograms. – Cell phones have already revolutionized the way people around the world communicate and do business. Thanks to advances being made at UCLA, they are about to do the same thing for medicine.
Low income men more likely to be diagnosed with advanced prostate cancer – Low-income men are more likely to present with advanced prostate cancers, most likely because they don’t receive screening services shown to reduce the diagnosis of later-stage cancers, a UCLA study found.
Colonoscopy significantly reduces death from left-sided colon cancer but not from right-sided. Physicians should advise patients of test limitations. – A new study finds that colonoscopy is strongly associated with fewer deaths from colorectal cancer. However, the risk reduction appears to be entirely due to a reduction in deaths from left-sided cancers.
New research suggests that genes that predispose people to obesity act in the brain and that perhaps some people are simply hardwired to overeat. – A genetic study of more than 90,000 people has identified six new genetic variants that are associated with increased Body Mass Index (BMI), the most commonly used measure of obesity. Five of the genes are known to be active in the brain, suggesting that many genetic variants implicated in obesity might affect behaviour, rather than the chemical processes of energy or fat metabolism.
If Brain MRI shows signs of Multiple sclerosis (MS), will the disease develop? – With more and more people having brain MRIs for various reasons, doctors are finding people whose scans show signs of multiple sclerosis (MS) even though they have no symptoms of the disease.
New breast imaging technology – breast specific gamma imaging – BSGI targets hard-to-detect cancers – Breast-specific gamma imaging (BSGI) is effective in the detection of cancers not found on mammograms or by clinical exam, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
US Radiologists are in better position to diagnose and treat self embedding disorder in teens, as some teens are wounding themselves and embedding objects such as paper clips and glass to cope with disturbed thoughts and feelings. – Minimally invasive, image-guided treatment is a safe and precise method for removal of self-inflicted foreign objects from the body, according to the first report on “self-embedding disorder,” or self-injury and self-inflicted foreign body insertion in adolescents.
ASGE encouraged by drop in colorectal cancer deaths. Prevention through screening and removal of precancerous polyps among key factors in saving lives. – The American Society for Gastrointestinal Endoscopy (ASGE) heralds the recent news of a decline in U.S. cancer deaths and incidence rates, with colorectal cancer among the top three cancers with significant declines.
Psychological interventions associated with breast cancer survival; Psychological intervention improves survival for breast cancer patients. – A new study finds that breast cancer patients who participate in intervention sessions focusing on improving mood, coping effectively, and altering health behaviors live longer than patients who do not receive such psychological support.
Soluble fibre, antispasmodics, and peppermint oil are more effective in the treatment of irritable bowel syndrome. – Fibre, antispasmodics and peppermint oil are all effective therapies for irritable bowel syndrome (IBS) and should become first-line treatments, according to a study on bmj.com.
