Knee Replacement Overuse Concerns


Knee Replacement Overuse Concerns

In the past two decades, the number of total knee replacements in the US has more than doubled, and there are concerns that not all of them are justified. Recent research seems to validate these concerns, suggesting that a third of the osteoarthritis patients in the US that undergo total knee replacements are inappropriate for the procedure. Most of them had only moderate symptoms and limited joint damage. Part of the problem appears to be a lack of a standard in criteria for evaluating potential knee replacement candidates.

Post-Op Pain Differs by Gender


Post-Op Pain Differs by Gender

Pain is a complex issue. There are physiological as well as psychological and cultural issues at play in the perception, tolerance, and admission of pain. This makes it a very difficult matter to study, but this does not deter researchers from attempting it, and what they have recently found is that men and women report different levels of pain after surgical procedures. Women tend to report greater pain after minor procedures, whereas men report more pain after major surgeries. More… Discuss

SLEEP-DEPRIVED SURGEONS NO MORE ERROR-PRONE


Sleep-Deprived Surgeons No More Error-Prone

Studies on the effects of fatigue on surgical outcomes have had mixed results, but one recent study indicates that missed sleep does not make surgeons more error-prone. The risk of complications from gallbladder removal surgery was found to be the same for patients whose surgeons had been up all night performing emergency surgery as for those whose surgeons were well rested. Complication rates were fairly low across the board. Researchers say the findings should ease the concerns of people requiring surgery. More…Discuss

 

Henry Molaison (1926-2008)Head Injuries and Brain Function Consequences


H.M.

Henry Molaison, better known as H.M., was an American memory disorder patient whose case played a key role in the development of theories regarding the link between brain function and memory. In 1953, after parts of his brain were removed to treat his otherwise intractable epilepsy, it was found that he was unable to form new long-term memories. He thus became the subject of numerous studies on brain function and amnesia. What did scientists learn about memory by studying H.M.? More… Discuss
