Reading The Brain Without Poking It
Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. Now, a University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don"t penetrate it.

Minority Lawmakers Call For 'Aggressive Solutions' To Health Disparities
"Black, Latino and Asian lawmakers want President Barack Obama to focus more on racial disparities reported in medical treatment as the White House works toward overhauling the nation"s health care system," the Associated Press reports. "Members of the Congressional Black Caucus sent Obama a letter last week calling for more attention to minority health problems" and are "expected to join lawmakers from Hispanic and Asian caucuses Tuesday at a news conference on Capitol Hill." They plan to "introduce an alternative health care proposal soon that would improve services in low-income areas, eliminate language barriers and improve data collection to help detect gaps in care for various racial and ethnic groups" (Evans, 6/9).

Highlights Of Pain Research

and four hours post-operatively. Total opiate consumption was also recorded. The result: There was significantly less post-operative pain in group A (Bupivacaine intra-articular and periportal skin infiltration), compared with group C (no infiltration) immediate postoperatively and one hour post-operatively, and compared with group B (Bupivacaine periportal skin infiltration) two hours and four hours post-operatively. There were no significant differences in visual analogue scores between groups B and C at any time-points. Group A used significantly less opiates post-operatively compared with group B or C but there was no significant difference in opiate use between groups B and C. Dr Bunn: "Intra-articular local anaesthetic significantly reduces post-operative pain, but at what cost to the chondral surface? Local skin infiltration of the arthroscopy portals does not significantly alter pain levels or opiate requirements. Avoidance of "intra-articular" local anaesthetic raises opiate requirements. We require improved alternative analgesic regimes." Abstracts: EFORT 2009 Abstract: Sharma A et al, Errors in prescription of regular medication in emergency surgical admissions-clinical audit.
