Health officials in Oklahoma are notifying 57 patients who tested positive for hepatitis C and three patients who tested positive for hepatitis B after visiting oral surgeon W. Scott Harrington's office in Tulsa and a city suburb, according to a joint statement issued Wednesday by the Oklahoma State Department of Health and the Tulsa Health Department.

Dentist's former patient: How could you? "This is a complex investigation," state epidemiologist Kristy Bradley said in the statement. "The next phase will include more in-depth interviews of persons who test positive to determine the likelihood that their exposure is associated with their dental surgical procedure at the Harrington practice. We will certainly continue to keep the public informed as we learn more." Mor

"We've been baking this bread for 60 years, and we're pretty good at it, buddy," said Kenneth Alexander, an infectious disease expert at the University of Chicago.

"I continue to be amazed that people bring this issue up," said Paul Offit, a pediatrician and noted University of Pennsylvania vaccine researcher. "There have been six exhaustive studies (of a possible link between thimerosal and autism). ... They each came back with a definitive answer: No. Three other studies were done to see if thimerosal caused any signs of mercury poisoning. All three answered: No."

Also, Protein Sciences Corp. of Meriden, Conn., landed a five-year, $147 million contract to develop a vaccine using its recombinant technology — flu proteins grown in insect cells. The hope is that the first doses would be available within 12 weeks of the beginning of a pandemic. That is about twice as fast as flu vaccine produced from eggs.

Rogobo, you make a welcome and important point. But reality is that this topic seems to give rise to insult because it has high stakes (precious cargo on board! kids! death and disease). If you think it's hard to hear a message while people are shouting insults, what's it like being deaf because your mummy got rubella while pregnant? I would put it like this: Notion 1: A world without effective serious infection vaccine is uglier and less pleasant than the alternative (polio, anyone?).  Notion 2: At a population level, vaccines improve outcomes more than they harm them.  Notion 3: At a population level, improved outcomes and the prospect of eradication is dependent on high individual participation. Notion 4: At an individual level, there is some risk associated with vaccination. Notion 5: Healthy people not taking the risks of vaccination are: (a) free riding on those who are taking the risks; (b) reducing the prospect of eradication; (c) increasing the prospect of passing infection to those medically incapable of taking the risk Notion 6: Individual liberty and freedom to choose might sometimes be trumped by requirements of public welfare Happy to have any of those notions challenged and discussed

HPV infection is the most common sexually transmitted disease — between 75 percent and 80 percent of females and males in the United States will be infected at some point in their lives. Most will overcome the infection with no ill effects. But in some people, infections lead to cellular changes that cause warts or cancer, including cervical, vaginal and vulvar cancers in women and anal cancers in men and women. A growing body of evidence suggests that HPV also causes throat cancers in men and women as a result of oral sex. HPV infections cause about 15,000 cancers in women and 7,000 cancers in men each year. And while cervical cancer rates have plunged over the past four decades because of widespread screening, anal cancer rates in men and women have been increasing. Head and neck cancers have also been increasing, with the share associated with HPV infection increasing rapidly — perhaps because oral sex has increased in popularity.
