I received many excellent submissions which I plan to post here in the coming months. by Amanda Carpenter In 1983, identical twin boys simultaneously received a contaminated blood transfusion immediately after birth, and were subsequently diagnosed with HIV-1. Years later, one of the twins is faring very well and has a near normal immune system, while the other is in poor health and has experienced many complications. How could the same virus, infecting two individuals at the same time, with the same genetic background, yield such different clinical courses? This unfortunate natural experiment has allowed researchers to study viral evolution while holding h... virology blog blogs http://www.medworm.com/rss/comments.php?id=4840508 Tue, 17 May 2011 14:12:31 +0100 4840508 http://www.medworm.com/index.php?rid=3976504&cid=t_151343_88_f&fid=38129&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2Flifeinthefastlane%2FWZHV%2F%7E3%2FgQDGzBkqyu4%2F Time to challenge that cerebral cortex and put on those 'mental' dancing shoes as we trip the light fantastic of medical trivia, and lift the latch on the cage of the tiger of tease...the Funtabulously, Frivolous Friday Five...dealing with glaucoma, blood transfusion, sick US presidents, nursery rhymes and venomous snakes!

The first systematic study of human herpesvirus 8 in U.S. blood donors found that the prevalence of detectable genomes of HHV-8, which causes Kaposi's sarcoma, is very low in healthy donors. According to the study, featured in the May issue of Transfusion, a sensitive and quantitative real-time polymerase chain reaction assay was used to detect HHV-8 DNA from purified CD19+ B lymphocytes from 962 randomly selected U.S. whole-blood donors.Read the abstract and editorial.

Somewhere, I heard that if you had been diagnosed with cancer and then also had chemotherapy, you were not eligible to give blood. I think about giving blood often and urge family members and friends to give. I have often wished that I could contribute to blood banks and drives, but truly believed that having had breast cancer eliminated me. Yesterday I decided I really didn’t know for sure and that I should look into it. On its list of eligibility requirements for blood donation, the American Red Cross states that people diagnosed with cancer can donate if the cancer was treated successfully and at least 12 months have passed with no cancer recurrence. This is a change from their p...

The HCC rate for males increased from 4.5 in 2001 to 5.4 in 2006, and the rate for females increased from 1.2 to 1.4 (Figure). During 2001--2006, the APC for males (3.6%) was significantly higher than the APC for females (2.3%).While the highest incidence rate was highest in Asian/Pacific Islanders (7.8 per 100,000 persons), the rate in this...

Pre-op physical… check… labs… check… packed the bag… check… donated your blood… check- but this is where the question comes into play. A new US study found that cardiac surgery patients who received blood transfusions of blood that had been stored for 2 weeks or less had lower rates of complications and death than those who received blood that was older. Were you instructed on when to donate? Did the nurse or case manager that prepared you for surgery advise you that the fresher your blood the better? Why would this be the case you ask? Older blood loses nitric oxide, an important agent in the delivery of oxygen to tissue cells. Another reason is that red blood cells b...

The guidance explores how doctors should deal with a range of dilemmas including abortion, the wearing of face-veils and male circumcision.  It also looks at patients’ own beliefs and how they can affect the doctor/patient relationship.  It aims to balance a doctors’ right to practise in accordance with their views and beliefs, and the patients’ right to receive timely and appropriate medical care.

Nitric oxide, which is critical in keeping blood vessels open, appears to begin breaking down as soon as blood goes into storage. Doctors have become increasingly worried about the number of heart attack and stroke patients that have received blood transfusions. "It doesn't matter how much oxygen is being carried by red blood cells, it cannot get to the tissues that need it without nitric oxide. If the blood vessels cannot open, the red blood cells back up in the vessel and tissues go without oxygen. The result can be a heart attack or even death,"&nb...
