Cone beam CT superior to mutidetector CT for detecting superior semicircular canal dehiscence

Cone beam CT is superior to mutidetector CT for detecting superior semicircular canal dehiscence or the so called third window (a small hole in the bony wall of the inner ear bone that can cause dizziness and hearing loss) and it uses half the radiation dose, a new study shows.

Symposium at EuroPRevent 2012 highlights benefits of oily fish consumption

Most people, whether healthy or having cardiovascular disease (CVD), would benefit from regular consumption of oily fish, concluded speakers at the EuroPRevent 2012 meeting. While eating whole fish undoubtedly offers the optimum approach for increasing omega-3 intakes in both primary and secondary prevention, delegates heard, supplements have a major role to play in increasing omega-3 intakes for people who do not like fish.

Cervical spine CT exams unnecessary for simple assault and ground-level fall victims

Cervical spine CT examinations are unnecessary for emergency department (ED) patients who are a victim of "simple assault" or who have a "ground-level fall", unless the patient has a condition that predisposes the patient to spine fracture, a new study finds.

New pressure-technology device effective in reducing incidence of PONV

In a peer-reviewed published study, a new medically engineered pressure-technology disposable adhesive device (Pressure Right-) developed by Pressure Point Inc. has clinically proven to enhance the efficacy of a popular prophylactic antiemetic drug combination in reducing the incidence of postoperative nausea and vomiting (PONV) among high-risk patients after major laparoscopic surgery procedures.

ENABLER-P Balloon Catheter System offers alternative to surgical revascularization

A new balloon catheter system could advance the endovascular approach to treating obstructed arteries in the leg, offering an alternative to surgical revascularization. Peripheral artery disease affects about 12 to 14 percent of the general population, and revascularization can be achieved through bypass surgery or a number of minimally invasive endovascular techniques that seek to reduce or eliminate symptoms of reduced blood flow by improving tissue perfusion.

Brain imaging for stroke is still occurring too slowly at many hospitals

The mantra in stroke care is "time is brain." With each passing minute more brain cells are irretrievably lost and, because of this, timely diagnosis and treatment is essential to increase the chances for recovery. While significant strides have been made to improve the response time of caregivers, a new study shows that a critical step in the process - imaging of the brain to determine the nature of the stroke - is still occurring too slowly at too many hospitals.

New clues about why immune system fails to kill tumors in mice

A pioneering approach to imaging breast cancer in mice has revealed new clues about why the human immune system often fails to attack tumors and keep cancer in check. This observation, by scientists at the University of California, San Francisco (UCSF), may help to reveal new approaches to cancer immunotherapy.

TA during PCI provides long-term outcomes for patients with acute STEMI

New research confirms thrombus aspiration (TA) during percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) provides long-term outcomes similar to conventional intervention with bare-metal or drug-eluting stents.

Study explains beneficial fat-fighting effects of black pepper

A new study provides a long-sought explanation for the beneficial fat-fighting effects of black pepper. The research, published in ACS' Journal of Agricultural and Food Chemistry, pinpoints piperine - the pungent-tasting substance that gives black pepper its characteristic taste, concluding that piperine also can block the formation of new fat cells.

Probiodrug AG, collaborators explain interplay of key suspects in Alzheimer’s

Probiodrug AG (Probiodrug), a biotech company developing products for the treatment of neurodegenerative and inflammatory diseases with a particular focus on Alzheimer's disease (AD), today announced its scientists and academics collaborators published seminal findings on the role of pyroglu Aβ in AD pathology in the May 2, 2012 online edition of the journal Nature (DOI: 10.1038/nature11060). The new findings add to the growing body of evidence that pyroglu Aβ plays a crucial role in the initiation of AD. In addition, the research results further elucidate the mechanism by which pyroglu Aβ triggers neuronal toxicity.
