A new study showing an estimated 7% of American teens and adults carry the human papillomavirus in their mouths may help health experts finally understand why rates of mouth and throat cancer have been climbing for nearly 25 years. The evidence makes it clear that oral sex practices play a key role in transmission. The new data, published online Thursday by the Journal of the American Medical Assn., are the first to assess the prevalence of oral HPV infection in the U.S. population.

Some girls may be more likely to overestimate the protection they receive from the HPV vaccine, new research shows. Human papillomaviris, the most common sexually transmitted infection, can infect the genital areas of men and women, cause genital warts and raise the risk of cervical cancer. The new study, published this week by the Archives of Pediatrics and Adolescent Medicine, looked at the perception of HPV risk among a population of 339 girls between age 13 and 21. At an average age of 16.8 years, 57.5% of these girls were sexually experienced, and most of them reported "continued need" to practice safe sex. However, a good 23.6% appeared to believe mistakenly that their risk of other sexually transmitted diseases was also lower -- even though the HPV vaccine does not protect against the rest of the pantheon of such diseases, such as HIV/AIDS, gonorrhea and syphilis.

Vaccination against human papilloma virus was recommended for U.S. girls almost five years ago. In October, a government advisory committee also recommended routine vaccination for boys ages 11 and 12. But vaccinating girls only makes the most sense, researchers said Tuesday. Using mathematical models, researchers in the Netherlands found vaccinating girls is the best way to reduce heterosexual transmission because girls have the highest prevalence of the virus. Immunizing the group with the highest prevalence achieves the largest population-wide reduction of the virus.

In a trial involving nearly 40,000 women in the Netherlands, testing for the human papillomavirus, or HPV, allowed doctors to detect abnormal cervical cells earlier -- and prevent more cases of cervical cancer -- than administering pap smears alone. In the study, which was published Wednesday in the journal Lancet Oncology, a team of researchers led by Dr. Chris J.L.M. Meijer of the VU University Medical Centre in Amsterdam randomly assigned women ages 29-56 into two groups. The first group received an HPV test as well as a pap smear; the second group, a pap smear alone. Five years later, both groups had HPV tests and pap smears.

A government panel now recommends that the vaccine against human papillomavirus should be routinely given to boys as well as girls. Our question is: What took so long? Gardasil, the vaccine developed by Merck, protects against the HPV strains most likely to cause cervical cancer. Because its purpose is to reduce this scourge, it always made sense to treat it as a public health issue and vaccinate those who might spread the virus along with those who might actually get sick.

The HPV vaccine routinely should be recommended for boys and young men because it clearly cuts the risk of cell changes that can develop into anal cancer, says the author of a study published Wednesday. Data from the paper appearing in the New England Journal of Medicine was presented earlier this year to health authorities who advise the Centers for Disease Control and Prevention on the nation's immunizationstrategy. These experts voted on Tuesday to recommend routine HPV vaccination to boys ages 11 and 12 and catch-up vaccination up to the age of 21. "The study is the first data looking at biomarkers in the development of anal cancer," said Dr. Joel Palefsky, a professor of medicine at UC, San Francisco, and the lead author of the paper.

The vaccine that protects against a sexually transmitted, human papilloma virus, should be routinely recommended to boys ages 11 and 12, a government advisory committee said Tuesday. The HPV vaccine is already advised for routine use in girls ages 11 to 12 to prevent cervical cancer. But a panel of health experts said that new data on the Gardasil vaccine's ability to curb the risk of anal cancer, particular among gay men, warrants adding boys to the list of people who should get the three-dose vaccine.

Despite Republican presidential candidate Michele Bachmann's recent charge that the HPV vaccine can cause "mental retardation," ongoing safety studies on the vaccine reveal no surprises, health officials said Tuesday. "We have no evidence" that HPV vaccination causes mental retardation, said Dr. Eileen Dunne, an epidemiologist at the Centers for Disease Control and Prevention, at a hearing of the Advisory Committee on Immunization Practices, a panel that advises the CDC. The committee voted 13-0 to recommend routine human papillomavirus vaccination for boys ages 11 and 12. The vote included a review of the safety of the vaccine, which has been in use among girls in the United States since 2006.

A vaccine that protects against the sexually transmitted human papillomavirus should be routinely given to boys ages 11 and 12 to prevent anal cancer, a government advisory committee has decided. Though many parents may not wish to contemplate the future sex lives of their pre-adolescent children, vaccinating them young is the best way to avoid the risk of the cancer-causing virus, experts said Tuesday. The recommendation is sure to ignite further debate among the Republican presidential candidates who have focused intently on whether the controversial vaccine, called Gardasil, is appropriate for girls — who receive it for prevention of cervical cancer — let alone for boys.

An independent federal panel and several other leading medical groups are proposing new guidelines for cervical cancer screening -- in the same month that the federal panel made news by recommending against routine PSA tests to screen for prostate cancer. Among the recommendations: that women over age 21 should undergo Pap smears to test for cervical cancer only once every three years, according to the U.S. Preventive Services Task Force. This syncs somewhat with a new set of proposed guidelines from the American Cancer Society, the American Society for Clinical Pathology and the American Society for Colposcopy and Cervical Pathology, also released Wednesday.
