Nephrogenic Systemic Fibrosis And Gadolinium-Based Contrast Agents
Even at very high doses, gadolinium-based contrast agents alone are not sufficient to cause nephrogenic systemic fibrosis (NSF) in patients with kidney problems, according to a study performed at the Mayo Clinic Florida, Jacksonville, FL. NSF is a rare and serious syndrome that leads to fibrosis of the skin, joints and even internal organs. Some research indicates NSF is caused by gadolinium-based contrast agents that are commonly used today during MR procedures.

Another Mystery In B Lymphocyte Development Solved By NYU School Of Medicine Pathology Researchers
A new study published online in Nature Immunology ahead of the June 2009 print issue has found that homologous immunoglobulin (lg) alleles pair up in the nucleus at stages that coincide with V(D)J recombination of the heavy and light chain (Igh and Igk) loci. Researchers led by Jane A. Skok Ph.D., assistant professor in the Department of Pathology at NYU School of Medicine and a member of the NYU Cancer Institute, showed that the V(D)J recombinase, which consists of the RAG1 and RAG2 proteins, mediates this pairing and helps ensure that only one allele undergoes recombination at a time (a process known as allelic exclusion).

CDC Reports 21,449 Cases Of Swine Flu, Including 87 Deaths In The USA
The Centers for Disease Control and Prevention (CDC), USA, in its latest update, dated Friday evening, 19th June, 2009, reports a total of 21,449 confirmed human cases of swine flu A(H1N1) infection, including 87 deaths. Authorities say the novel A(H1N1) influenza virus has not mutated and is not more virulent (aggressive) than most normal seasonal human flu viruses. However, health services are bracing themselves for a busy flu season this winter as the swine flu virus will have been circulating for several months, but will still be a relatively novel one.

National Athletic Trainers' Association (NATA) Offers Guidelines For Management Of Serious Spine Injuries On The Athletic Playing Field

According to a new position statement from the National Athletic Trainers" Association (NATA), proper management of acute spinal injuries on the athletic playing field is crucial, given that sports participation constitutes the second most common cause of spinal cord injuries for Americans age 30 and younger. Sports medicine providers and others on the sidelines need to be familiar with the appropriate acute-management guidelines for athletes with cervical-spine injuries. Published in this month"s Journal of Athletic Training, NATA"s scientific publication, the position statement provides detailed guidelines for the immediate treatment and transport of athletes who are injured on the playing field. "Serious spinal injuries can be devastating, due to the high incidence of long-term neurological impairment and premature death," said Erik E. Swartz, PhD, ATC, lead author of the statement. "That"s why we urge players and parents, as well as coaches and medical personnel, to become better versed about how to prevent these types of injuries and how to care for injured athletes and safely prepare them for transport to a hospital." According to "National Athletic Trainers" Association Position Statement: Acute Management of the Cervical Spine-Injured Athlete," athletic trainers and other health care professionals, coaches, athletes, and people on the sidelines should be aware of, and follow, these guidelines in order to avoid injury or exacerbate spinal injuries that have already occurred: 1. Understand how cervical spine injuries occur and be fully aware of the importance of avoiding contact with the head in any sport, and emphasizing proper techniques of tackling or checking in football, ice hockey and lacrosse. 2. Keep current on all pertinent safety rules enacted for the prevention of cervical spine injuries. 3. Properly maintain all sporting equipment, and wear and use equipment as intended by the manufacturer. 4. The importance of a proper fit when it comes to equipment cannot be understated, because correctly fitted helmets and other equipment often helps with spine stabilization in the event of an injury. 5. Immediate care by knowledgeable health care providers, such as athletic trainers, is critical to the successful treatment of an athlete with a spine injury, so make sure these types of professionals are on the sidelines. 6. Ensure that an emergency action plan is in place and has been reviewed by all medical personnel, administrators, coaches and players. 7. Non-medical professionals should refrain from touching or moving an athlete who might have a spinal injury and should never remove any helmets, pads or other equipment from an injured athlete; the team"s athletic trainer and/or other on-site medical staff will assess the injured athlete and determine whether he or she requires an ambulance. While football is associated with the greatest number of catastrophic spinal injuries for all U.S. sports, skiing, rugby, gymnastics, swimming and diving, track and field (e.g., pole vaulting), cheerleading and baseball also involve activities that place participants at risk for spine injuries. "Sports participation is a leading cause of these types of injuries, especially in younger people," Swartz said. "An average of eight catastrophic cervical spine injuries occurred annually in football alone between 1997 and 2006." "The athletic trainer is very often the first responder when an athlete goes down on the field," said Swartz. "NATA"s review of precautions and practices for immediate care helps ensure athletic trainers and other health care professionals understand the most effective methods to care for athletes with cervical spine injuries."
