Dental Procedures not a Risk Factor for Artificial Joint Infections

Good news for patients with prosthetic joints undergoing dental procedures.

There has been much debate for decades as to whether dental procedures increase the risk of infection in those who have had total joint replacements. A new prospective, case-controlled study of patients at the Mayo Clinic has found that neither high-risk or low-risk dental procedures performed within 6 months to two year of hospital admission increased the risk of infection. Antibiotic prophylaxis prior to dental procedures did not lower risk of infections, either.

PositiveTip: If you have had a joint replacement, a healthy lifestyle may be your best protection from infections.

Household Transmission of 2009 H1N1 Flu

Household transmission of 2009 H1N1 highest in those under 18 years old.

While many "top" issues could be listed, the 2009 H1N1 influenza pandemic has received enormous press in both the medical and lay press. This epidemic has taught us a great deal. As of this date, there have been fewer deaths than from previous flu pandemics--and that is the good news! A new analysis of household transmissibility of H1N1 showed that persons 18 years of age or younger were twice as susceptible as those 19-50 years of age; and those 50 or older were even less susceptible. Most transmissions occurred fairly quickly.

Fruits and Vegetables Really Do Matter!

Can you fight the flu and other infections with food?

Many of us are still waiting for the swine-flu vaccine to reach our locality. Are there foods we should be eating to help us fight off infections and disease? Absolutely! A lot of research is demonstrating that a nutrient-rich diet is necessary to help effectively fight off disease. How can we be assured we are getting enough? Tests are expensive and often unreliable.

Most nutrition experts agree the best way to get all the nutrients our bodies need is through a balanced diet based on plenty of fruits and vegetables, whole grains, legumes, and some nuts. Taking individual supplements and vitamin pills can upset the delicate balance between the nutrients or be toxic. Getting them from good food makes overdosing almost impossible.
