Fungal contamination in breast implant surgery: A rare, preventable complication

Although apparently uncommon, fungal contamination of saline-filled breast implants is readily preventable, according to a study in the July 1 issue of The Journal of Infectious Diseases, now available online. The key steps are to use closed systems for filling the devices and to adhere to the strict moisture control and operating room ventilation standards in force at major hospitals. The potential benefits of these precautions could be considerable, since 265,832 women in the United States underwent cosmetic or reconstructive breast surgery in 2000 alone, and most received saline-filled implants. more  

Vaccine targets tumors where they live

Vaccine strategies are being designed to battle cancer, but their use for metastatic melanoma is a challenge. Effective vaccines against established tumors require tumor-reactive T cells to traffic to the sites of the tumors and are locally activated there in order to kill cancer cells. A problem is that the T cells lose their tumor-killing power once they reach the environment surrounding the tumor. This happens because T cells decrease stimulatory molecules including one called B7.1. more

The link between passive and active smoking and breast cancer

Breast cancer is one of the most commonly diagnosed cancers among women in Western countries. In North America, for example, there are an estimated 233,000 new cases every year and 45,000 deaths. Despite the well-characterized role of genetics and reproductive risk factors, as well as the suggested roles of physical activity and alcohol, more than half of breast cancer risk remains unexplained. more  

Immune-system cells may promote chronic infections in cystic fibrosis

Cells sent to fight infections in the lungs of cystic fibrosis patients actually enhance the development of permanent bacterial infections, according to researchers at National Jewish Medical and Research Center. Infections with the bacteria Pseudomonas are a major cause of sickness and death in cystic fibrosis patients. The findings, published in the June issue of Infection and Immunity, suggest new treatment strategies for patients with cystic fibrosis. more

Diabetes knowledge has little effect on improving outcomes  

A new study by Duke Clinical Research Institute researchers finds little relationship between what a diabetic patient knows about the disease and control of its associated cardiovascular risk factors or how well the patient ultimately fares. more

Whooping cough vaccine effective, safe for teens and adults 

The Journal of the American Medical Association today announced that a study to be published in the June 22/29 issue found that a new vaccine against whooping cough is effective in teens and adults, carriers of the contagious respiratory disease so dangerous to infants. Until recently, teens and adults have been unable to be vaccinated with available pediatric whooping cough vaccines due to safety concerns. more

Prescription of heroin is less costly for society

Prescribing methadone plus heroin to chronic, treatment resistant addicts is less costly than methadone alone because it reduces criminal behavior, finds a study in this week’s BMJ. more
