New guidelines: Common drugs can calm essential tremor

Imagine not being able to hold a glass, tie your shoelaces or write a check. For people with the common movement disorder known as essential tremor, simple tasks requiring fine motor coordination become increasingly difficult, sometimes even impossible. Three times more prevalent than Parkinson's disease, essential tremor involves uncontrollable shaking of the hands, arms, head or voice. The largely hereditary neurological condition can begin in early adulthood and worsen with age. more  

Vaginal cancer detected more often with PET than CT scans

In patients with vaginal cancer, PET scans detected twice as many primary tumors and cancerous lymph nodes as did CT scans, according to researchers at Washington University School of Medicine in St. Louis. At this time, however, Medicaid, Medicare and many private insurers specify CT (computed tomography) for diagnosing and monitoring this cancer. more

Unease over guidelines that label 9 out of 10 people as sick

Guidelines that set ever lower thresholds for "normal" blood pressure and cholesterol mean that 90% of people over 50 could be labelled as sick, warn doctors in this week's BMJ. more  

Johns Hopkins scientists use gene therapy to prevent heart arrhythmias from stem cell transplants

Heart specialists at Johns Hopkins believe they have figured a way around a persistent barrier to successful adult stem cell therapy for millions of Americans who have survived a heart attack but remain at risk of dying from chronic heart failure. more

Therapy may not be necessary for autoimmune hepatitis with no symptoms  

It is not uncommon for patients with autoimmune hepatitis (AIH), a disease in which the patient's own immune system attacks the liver, to have no symptoms. Such cases are being diagnosed more frequently due to the increased practice of administering routine liver enzyme and antibody tests. Whether or not to treat asymptomatic AIH remains unclear--therapy with immunosuppressants could potentially slow progress of the disease but involves side effects that are sometimes toxic. more

Online analytical toolbox for cancer and other biomedical research 

A new website, http://biogeowarehouse.cse.psu.edu, offers a prototype for online access to an analytical toolbox that enables biomedical researchers to integrate dissimilar data from a variety of sources and extract the most useful information from it by posing queries. more

Researchers discover mechanism that may enable stem cell-based treatment for eye disorders

In discovering a protein that helps organize the development of the retina, UC Irvine researchers have found a new molecular mechanism that may allow for stem cell-based therapies to treat eye disorders such as retinal degeneration. more

 

Do narrow guidelines classify too many of us as sick or at risk?
