Surgeon uses new method to remove pituitary tumors

Removing pituitary tumors through the nasal cavity rather than using the classic approach beneath the upper lip offers patients a minimally invasive alternative with similar results, less discomfort and faster recovery, a new UCLA study indicates.

The findings, published in the February 2003 edition of the peer-reviewed Journal of Neurosurgery, quantify the advantages of the direct endonasal approach over the sublabial procedure, regarded as the surgical standard for more than 40 years.

Attention chocolate lovers: More evidence your favorite treat is good for the heart

Just in time for Valentine’s Day, a report published in the February issue of the Journal of the American Dietetic Association says that chocolate is good for your heart.

Researchers at the University of California at Davis reviewed a number of recent studies on chocolate – particularly dark chocolate – and its health benefits. They found that flavan-3-ols, the main flavonoids found in cocoa, are associated with a decreased risk of cardiovascular disease.

“Cocoa contains th

Mouse genetic model for spongiform brain diseases

Some mice with a genetic mutation for mahogany-colored coats also develop spongiform degeneration of brain tissue, similar to mad cow disease. Because of this oddity, the mice could be valuable animal models for human disorders, such as Parkinson’s and Alzheimer’s diseases, according to geneticists at Cornell and Stanford universities.

The surprising discovery in a mouse strain known to geneticists since the 1960s is reported in the latest issue of the journal Science (Jan. 31, 2003

Removing Portion of Spleen Effective in Treating Inherited Childhood Anemias

Researchers from Duke University Medical Center and the Medical College of Wisconsin have shown that removing a portion, instead of all, of the spleen, can successfully treat children with a variety of congenital anemias while preserving important splenic immune function.

In the largest study of its kind in the U.S., the researchers performed the surgery, known as a partial splenectomy, on 25 children with congenital forms of anemia caused by abnormal red blood cells. Typically, these

Minimally invasive procedure fixes heart defect that allows blood clots to reach the brain

When 29-year-old Eric Lange suddenly experienced several hours of mental confusion last July, physicians at Cedars-Sinai Medical Center naturally ordered brain scans and carotid artery studies in their first search for a cause. With the initial exams turning out OK, Eric’s neurologist pursued other clues and ended up finding a heart defect called a patent foramen ovale, or PFO. A blood clot was believed to have slipped through the defect and out of the normal route of circulation that would

cean surface saltiness influences el nino forecasts

NASA sponsored scientists have discovered by knowing the salt content of the ocean’s surface, they may be able to improve the ability to predict El Nino events. Scientists, studying the western Pacific Ocean, find regional changes in the saltiness of surface ocean water correspond to changes in upper ocean heat content in the months preceding an El Nino event. Knowing the distribution of surface salinity may help predict events.

Salinity and temperature combine to dictate the ocean’s dens
