Source: www.mynews13.com Author: Rebecca Turco Despite studies from the CDC showing the effectiveness of the HPV vaccine at preventing certain types of cancer, some parents are still hesitant to get their children vaccinated. 92% of almost 35,000 cancers could be prevented by vaccine Doctor: Some parents may think vaccine promotes sexual behavior County Health Departments offer HPV vaccine for free Dr. Raul Pino, the interim administrator of the Orange County Health Department, wants to change that. Among the estimated 34,800 cancers probably caused by the human papilloma virus between 2012 and 2016, an estimated 92% could be prevented by the vaccine, according to the Centers for Disease Control and Prevention. "We have a vaccine that prevents some type of cancers, and now we're questioning if we should take the vaccine," he said. "It will not only prevent penile cancer or vaginal cancer or cervical cancer, but also oral, esophagus and tonsils. "So what are we waiting for?" Pino thinks some parents might be hesitant because of the widely spread, but disproven, belief that vaccines are linked to autism. Then, there are other parents who think giving their child the vaccine is promoting sexual behavior. HPV is the most common sexually transmitted infection. "The reality is, I think what the parents have to present to themselves in this debate, is what is the paramount objective here?" Pino said. "Is the paramount objective to offer protection to the individual, or is the paramount objective to prevent the behavior?" Officials recommended that children [...]
Source: www.precisionvaccinations.com Author: Don Ward Hackett, Fact checked by Robert Carlson, MD & Danielle Reiter, RN Does the HPV vaccine protect against oral infections? That's the question a new National Cancer Institutes (NCI) funded clinical trial of the Gardasil 9 vaccine hopes to answer. This extensive study will determine whether the Gardasil 9 vaccine can prevent persistent oral HPV infections among men who are Human Immunodeficiency Virus (HIV) positive, said the NCI online on October 8, 2019. Oral HPV infections and HPV-related oral cancers are common in men and among HIV-positive individuals. Gardasil 9 is the most recent formulation of the Human Papolivirus (HPV) vaccine, which covers 5 additional cancer-causing HPV types. There are over 100 types of HPV. “We are hoping that if we show the efficacy of the vaccine, that vaccinating both males and females will ultimately reverse” the rising incidence of HPV-related oropharyngeal cancers, said one of the trial’s lead investigators, Anna Giuliano, Ph.D., of Moffitt Cancer Center. The trial is one of several within the US–Latin American–Caribbean Clinical Trials Network (ULACNet), an NCI-led effort to reduce the burden of HPV-related cancers in HIV-positive individuals. This new study intends to build relevant insights upon a June 2017 study found that vaccination against HPV may sharply reduce oral HPV infections that are a major risk factor for oropharyngeal cancer, a type of head and neck cancer, says the NCI. The 2017 study found that the prevalence of oral infection with 4 HPV types, including two high-risk, or cancer-causing, [...]

CreditCreditKarsten Moran for The New York Times When Theresa Gucciardo-Perry discovered a cracked crown in her mouth in April, she dreaded the idea of going to a dentist to get it replaced. The Cortlandt Manor, N.Y., resident has undergone more than 18 root canal procedures; she also has five implants, with crowns on all but her front teeth. She hated the procedure in which trays of a gag-producing, putty-like substance were stuffed into her mouth to make impressions. “The putty material is just absolutely gross — I want to throw up,” said Ms. Gucciardo-Perry, 55. “And the crown never fit right. I always had to go back.” But this time, she sought care at the Touro Dental Health clinic, part of the Touro College of Dental Medicine in Hawthorne, N.Y., where students learn the latest state-of-the-art techniques. There, her teeth were digitally scanned with the wave of a wand — rather than a bulky goop-filled tray — and a crown was built digitally. It fit perfectly. “I was amazed — totally amazed,” said Ms. Gucciardo-Perry. Digital scanning is among a number of advances being adopted by the dental industry as the sector undergoes a technological metamorphosis. Among the latest innovations: The use of digital scanners and 3-D printers to offer same-day crown replacements, smart toothbrushes that talk back [...]
Source: Infectious Disease Advisor Date: September 30th, 2019 Author: Zahra Masoud Oral human papillomavirus (HPV) prevalence has decreased in unvaccinated men, possibly as a result of herd protection, but the incidence of such infection has remained unchanged in unvaccinated women from 2009 to 2016 in the United States, according to a study published in the Journal of the American Medical Association. Since 2011 for women and 2006 for men, prophylactic HPV vaccination for prevention of anogenital HPV infection has been recommended for routine use in the United States. Previous studies have demonstrated that this vaccine has high efficacy in reducing the prevalence of oral HPV infection. However, the vaccine is not indicated to prevent oral HPV infection or oropharyngeal cancers because there are few results from randomized trials. Further, there has been a lack of surveillance studies reporting on herd protection against oral HPV infection, which is defined as a form of indirect protection from infectious diseases that occurs when a large percentage of the population has become immune/vaccinated, thereby providing protection for individuals who are not immune/not vaccinated. Therefore, this study investigated evidence for herd protection against oral HPV infection in unvaccinated men and women in the United States using temporal comparisons of oral HPV prevalence for 4 vaccine types and 33 non-vaccine types. This study was conducted across 4 cycles (from 2009 to 2016) of the National Health and Nutrition Examination Survey (NHANES), using a cross-sectional, stratified, multistage probability sample of the civilian population in the United States. For the examination [...]
Source: medicalxpress.com Author: Emma McKinney, University of Birmingham Scientists at the University of Birmingham have found an anti-malarial drug was effective in treating head and neck cancer in mice. The drug quinacrine was used extensively to prevent and treat malaria in soldiers fighting in mosquito-ridden areas during World War Two. It is similar to the quinine that makes tonic water glow, has minimal side-effects, and is now used for treating parasite infections and other conditions. Each year around 11,900 people are diagnosed with head and neck cancer in the UK. Current treatment relies heavily on debilitating surgery and toxic chemotherapy, but despite this, it has a poor outcome with three to seven in 10 people surviving their disease for five years or more. The drug, quinacrine, was tested through a number of methods, including on cell cultures, in tumour biopsies from patients with head and neck cancer, and in mice. The research results, published in Oncotarget, show that in mice quinacrine can make standard chemotherapy more effective—suggesting a lower dose may be used, reducing toxic side effects. The results also showed the drug to be effective at reducing the growth of cancer cells grown in the lab, and in tumors. Significantly, the research in mice showed a combination therapy of quinacrine and chemotherapy, and so allowed for the chemotherapy dose to be halved while still maintaining the same impairment of tumor growth. Lead author Dr. Jennifer Bryant, of the University of Birmingham's Institute of Head and Neck Studies and Education, [...]
Source: www.usnews.com Author: Steven Reinberg Ten years after radiation treatment for head and neck cancer, some patients may develop problems speaking and swallowing, a new study finds. These problems are related to radiation damage to the cranial nerves, the researchers explained. The condition is called radiation-induced cranial neuropathy. "We had always thought that radiation did not damage cranial nerves because they get treated in every patient with head and neck cancer, and we do not see cranial neuropathy that commonly," said Dr. Thomas Galloway, of the department of radiation oncology at the Fox Chase Cancer Center in Philadelphia. "What our data is suggesting is that a small percentage of people do get cranial nerve damage from treatment, but it occurs after a long latency period," Galloway said. For the study, the researchers collected data on 1,100 patients who had radiation for head and neck cancer between 1990 and 2005. Among these patients, 112 were followed for at least 10 years. Of the 112 patients, 14% developed at least one cranial neuropathy. The median time until the condition was seen was more than seven years. It took some patients more than 10 years to develop the problem, the findings showed. Curing the initial cancer is the most important concern, Galloway said. But these patients need to be followed for the rest of their lives, if possible, he added. The report was published recently in the journal Oral Oncology.
