Single Celled Organism Helps In Understanding How Anesthesia Works

Experiments in one of the oldest forms of life on Earth are helping to answer basic questions about how general anesthesia works, according to a study in the January issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS). "Although the anesthetizing properties of ether have been known for over 150 years, scientists still do not know how ether and the other inhaled anesthetics act, " comments Dr. Steven L. Shafer of Columbia University, Editor-in-Chief of Anesthesia & Analgesia. "One challenge has been the diverse nature of substances that produce anesthetic effects, ranging from an atom (xenon), to a simple molecule (nitrous oxide), to a variety of organic solvents.

Early Relationships Influence Teen Pain And Depression

Angst could be more than a rite of passage for insecure teenagers, according to a study published in The Journal of Pain. Researchers from the Universit√ de Montr√ al, the Sainte-Justine University Hospital Center and McGill University have discovered that insecure adolescents experience more intense pain in the form of frequent headaches, abdominal pain and joint pain. These teens are also more likely to be depressed than peers with secure attachments. Dr. Isabelle Tremblay, a researcher at the Universit√ de Montr√ al and its affiliated Sainte-Justine University Hospital Center, and Dr. Michael Sullivan, a psychology professor at McGill University, launched this study to build on previous findings that childhood experiences play a major role in the relationships people develop in later life.

Ether Discovery Was Almost Made Earlier

The successful use of ether to anesthetize patients was the first great milestone in the history of surgical anesthesia. But the discovery might have occurred earlier and medical history written differently but for a scientific error by another physician, according to an article in the January issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS). In the new article, Martha E. Stone and colleagues of Harvard Medical School offer an account of Elton Romeo Smilie and his near-miss as the discoverer of ether anesthesia. The article, drawn from research by the historian Richard J. Wolfe, suggests that Smilie might actually have been the first to use ether to anesthetize patients only he didn't realize that ether was the cause of the anesthetic effect.

DURECT Reports Positive Phase IIb Data From POSIDUR TM Clinical Program

DURECT Corporation (Nasdaq: DRRX) announced positive results from a 60 patient Phase IIb clinical trial of POSIDUR(TM), a proprietary product under development for the treatment of post-surgical pain. Top line results from this study of patients undergoing arthroscopic shoulder surgery showed a consistent reduction of pain scores (as measured by mean pain intensity on movement AUC, time normalized under the curve, during the period 0 to 72 hours post-surgery) in parallel with a reduction of opioid use (as measured by the amount of opioids taken in the three days post-surgery) in favor of POSIDUR versus placebo. These reductions were not statistically significant given the size of the study.

The Holiday Rush Can Be A Pain In The Neck‚ And Back‚ And Shoulder‚ Learn How To Prevent It

To most of us the holiday season is all about tradition, fun, and family, but if we're not careful, the holidays can also be a pain in the neck-literally-says the American Physical Therapy Association (APTA). Typical holiday activities, such as shopping "till you drop, " lifting heavy boxes and presents, and countless hours of cooking and baking, can cause muscles to work harder than usual, many times resulting in neck, shoulder, and back pain. This holiday season APTA recommends taking precautions-from distributing the weight of shopping bags equally on both sides of your body to lifting boxes carefully-in order to keeps aches and injuries at bay.

Children With Cancer Have A High Probability Of Survival In Germany

Internationally viewed, medical care in Germany for children with cancer is very good as far as survival is concerned. However, other aspects, such as quality of life, pain, and long-term consequences of the disease are still insufficiently investigated in studies. This is the conclusion of the Institute for Quality and Efficiency in Health Care (IQWiG) in its final report published on 16 October 2009. Establish mandatory quality standards Every year in Germany approximately 1800 children under 15 years of age are diagnosed with cancer. In order to provide them with the best possible care, the Federal Joint Committee (G-BA) drew up a quality assurance agreement in 2007 (Quality Assurance Agreement on Paediatric Oncology).

Initiative Could Result In Paradigm Shift In The Care Of Sickle Cell Patients

The Medical College of Georgia is leading an initiative that could result in a paradigm shift in the care of patients with sickle cell disease. Morehouse University School of Medicine and University of Florida are partners in the initiative that is enlisting primary care physicians across Georgia to serve as "medical homes" for patients, changing how patients are treated when a pain crisis sends them to the hospital and seeking better prevention and treatment strategies for the pain and organ damage caused by the genetic disease affecting 1 in 500 blacks in the United States. "This is an exciting opportunity to really take on sickle cell disease from many angles: from ensuring that patients get regular medical care to improving hospital care to dissecting why patients respond to pain and analgesics differently, " said Dr.

New Clues Emerge For Understanding Morphine Addiction

Scientists are adding additional brush strokes to the revolutionary new image now emerging for star-shaped cells called astrocytes in the brain and spinal cord. Their report, which suggests a key role for astrocytes in morphine's ability to relieve pain and cause addiction, appears online in ACS' Journal of Proteome Research, a monthly publication. In the study, Piotr Suder and colleagues point out that nearly everyone viewed astrocytes - the most abundant cells in the brain - as supporting actors in the drama of brain activity. Scientists thought astrocytes simply propped up neurons, nerve cells that transmit signals, and kept them in proper position.

Study Explores Doctors' Views On Infants And Chronic Pain

A team of Canadian researchers probed 45 pediatric clinicians to learn about possible indicators that could help identify infants with chronic pain and provide guidance on how to differentiate chronic pain from lingering pain caused by medical procedures. At the outset of their study, the authors (representing several Toronto medical centers) noted there is no clear definition for chronic pain in infants and no validated assessment measures. As a result, long-term pain may be inadequately managed in this highly vulnerable population. The purpose of the research, therefore, was to gather and analyze opinions of experienced pediatric clinicians on parameters that could help define and assess chronic pain in infancy.

A Cup Of Brazilian Mint For Pain Relief

For thousands of years it has been prescribed by traditional healers in Brazil to treat a range of ailments from headaches and stomach pain to fever and flu. Now for the first time, researchers at Newcastle University have been able to scientifically prove the pain relieving properties of Hyptis crenata - otherwise known as Brazilian mint. Testing this ancient South American herb on mice, the team led by researcher Graciela Rocha was able to show that when prepared as a 'tea' - the traditional way to administer the medicine - the mint was as effective as a synthetic aspirin-style drug Indometacin. The research was presented at the 2nd International Symposium on Medicinal and Nutraceutical Plants in New Delhi, India, and will appear in the society's journal Acta Horticulturae.
