A new study finds that half of men in America are infected with the HPV virus. Dr. Jon LaPook reports on the growing concern that the virus in men could be responsible for an increase in head and neck cancers.
HPV Affects Half Of U.S. Men
A study out [yesterday] in The Lancet by Moffitt Cancer Center researcher Anna Giuliano, Ph.D., and her colleagues finds that 50 percent of men ages 18 to 70 in Brazil, Mexico, and the U.S. have genital infection with human papillomavirus (HPV). HPV is the virus that causes cervical cancer in women. It also causes warts and cancer of the genitals and anus in both men and women. Over the past several years, researchers have realized that the virus can also cause cancer of the head and neck.
Aimee R. Kreimer, Ph.D., of the National Cancer Institute, estimates that about 65 percent of the approximately 8,000 cancers of the tonsils and base of the tongue (oropharynx) seen in the U.S. in 2010 were from HPV infection; eighty percent of these are in men. The rates for HPV-associated cancers like these are increasing; for sites like the mouth and larynx that are associated with tobacco and alcohol use, the rates are decreasing (though still too high since too many people still smoke and abuse alcohol).
An infection rate of 50 percent for a virus that can cause cancer sounds scary. But knowing a few more facts about HPV helps put the risk in perspective. About 90 percent of men and women infected with HPV virus get rid of it on their own within about two years. There are many different strains of HPV — some that cause cancer and some that don’t. Only about 6 percent of men have genital infection with HPV 16 — the strain linked to more than 90 percent of cancers of the head and neck. And only about 0.6 percent of men have HPV 16 in specimens taken from their mouths; what percentage of those men go on to develop head and neck cancer is unknown. Read more »

Healthcare costs are a perennial issue for employers and employees. There are a variety of approaches out there designed to improve health status and health outcomes and reduce costs at the same time. Proponents of a variety of approaches have been featured here on HealthBlawg in the past.
I recently had the opportunity to speak with George Pantos, of the Healthcare Performance Management Institute, a brand-new organization on the scene, founded by a group of folks who have developed tools for managing these costs. Read more »

An article in the New York Times this week looks at a raft of new public health initiatives passed by Congress that are aimed at boosting disease prevention. Examples include requiring restaurants with at least 20 locations to include nutrition information on their menus and mandating employers with at least 50 employees to allow new mothers to express breast milk at work. In addition, Medicaid will now cover smoking cessation counseling for pregnant women and Medicare beneficiaries will be eligible for an annual physical. The initiatives are expected to eventually save money by decreasing the country’s chronic disease burden. (New York Times)
Researchers from Johns Hopkins University recently did a study applying physicians’ ethical codes to the conduct of the fictional doctors on “Grey’s Anatomy” and “House, M.D.” Perhaps to no one’s surprise, TV doctors are behaving very badly. As the abstract of the study states, both shows feature “egregious deviations from the norms of professionalism and contain exemplary depictions of professionalism to a much lesser degree.” (Philadelphia Inquirer, Journal of Medical Ethics)

H/T to MedGadget who’s post introduced me to “bioactive sutures.” What a great idea by the Johns Hopkins biomedical engineering students!
……have demonstrated a practical way to embed a patient’s own adult stem cells in the surgical thread that doctors use to repair serious orthopedic injuries such as ruptured tendons. The goal, the students said, is to enhance healing and reduce the likelihood of re-injury without changing the surgical procedure itself.
The project team of 10 undergraduates focused on Achilles tendon injuries which require repair in approximately 46,000 people in the United States every year. The surgery may fail in as many as 20%. Recovery can take up to a year even with successful surgery. If this new suture speeds healing and lowers failure rates – what potential!
At the site of the injury, the stem cells are expected to reduce inflammation and release growth factor proteins that speed up the healing, enhancing the prospects for a full recovery and reducing the likelihood of re-injury. The team’s preliminary experiments in an animal model have yielded promising results, indicating that the stem cells attached to the sutures can survive the surgical process and retain the ability to turn into replacement tissue, such as tendon or cartilage……………
As envisioned by the company and the students, a doctor would withdraw bone marrow containing stem cells from a patient’s hip while the patient was under anesthesia. The stem cells would then be embedded in the novel suture through a quick and easily performed proprietary process. The surgeon would then stitch together the ruptured Achilles tendon or other injury in the conventional manner but using the sutures embedded with stem cells.

A team at Johns Hopkins has coordinated the world’s largest kidney swap, involving sixteen patients in multiple medical centers across the US. One of the donors was the vice president of human resources at Johns Hopkins Health System, a woman who has promoted organ donation and finally got a chance to do the ultimate charity work herself.
Johns Hopkins reports:
An altruistic donor started the domino effect. Altruistic donors are those willing to donate a kidney to any needy recipient. Just like falling dominoes, the altruistic donor kidney went to a recipient from one of the incompatible pairs, that recipient’s donor’s kidney went to a recipient from a second pair and so on. The last remaining kidney from the final incompatible pair went to a recipient who had been on the United Network for Organ Sharing (UNOS) waiting list.
As part of this complex procedure, Johns Hopkins flew one kidney to Henry Ford, one kidney to INTEGRIS Baptist and one kidney to Barnes-Jewish, In exchange, Henry Ford, INTEGRIS Baptists and Barnes Jewish each flew a kidney to Johns Hopkins.
The 16 surgeries were performed on four different dates, June 15, June 16, June 22 and July 6. The 10 surgeons in charge included four at Johns Hopkins, two at INTEGRIS Baptist, two at Barnes-Jewish and two at Henry Ford.
Johns Hopkins surgeons performed one of the first KPD transplants in the United States in 2001, the first triple-swap in 2003, the first double and triple domino transplant in 2005, the first five-way domino transplant in 2006 and the first six-way domino transplant in 2007. Johns Hopkins also performed the first multihospital, transcontinental three-way swap transplant in 2007 and the first multihospital, transcontinental six-way swap transplant in 2009.
Nearly 100 medical professionals took part in the transplants, including immunogeneticists, anesthesiologists, operating room nurses, nephrologists, transfusion medicine physicians, critical care doctors, nurse coordinators, technicians, social workers, psychologists, pharmacists, financial coordinators and administrative support people.
