Supreme Court Rules Against Dental Board Regarding Teeth Whitening

Posted on Thursday, February 26, 2015

In a 6–3 vote, the Supreme Court ruled yesterday that North Carolina's dental board violated the Sherman Antitrust Act when it shut down nondentists who were whitening teeth in malls and beauty shops because the board, composed mostly of practicing dentists, was not actively supervised by the state. Active supervision, the court said, would have shielded the board from a Sherman violation.

In the wake of the high court’s decision, state medical boards may now find it harder to fence off the practice of medicine from nonphysicians.

"[The Sherman Act] does not authorize the states to abandon markets to the unsupervised control of active market participants, whether trade associations or hybrid agencies," the court said, upholding a move by the Federal Trade Commission (FTC) to block the dental board's actions in the name of fair competition.

Dissenting from the majority opinion were Associate Justices Samuel Alito Jr, Antonin Scalia, and Clarence Thomas.

The American Medical Association (AMA) and other medical societies had asked the Supreme Court to hear the case—and uphold the decision of the North Carolina dental board—in light of the antitrust implications for state medical boards.

"If state licensing decisions are subject to invalidation by federal agencies with no particular expertise in the healing arts, then those federal agencies will become the final arbiters of matters of public safety, tasks that they are ill-equipped to perform," the AMA and its allies stated.

The medical societies warned that if the FTC got its way, medical boards might be loath to crack down on nonphysicians engaged in "the illegal practice of medicine" for fear of triggering an antitrust suit. They cited the example of nurse practitioners who provide services that were beyond their qualifications without any physician supervision.

Rallying behind the FTC in the Supreme Court case were the American Nurses Association, the American Association of Nurse Practitioners, the American Association of Nurse Anesthetists, the American College of Nurse Midwives, and the National Association of Clinical Nurse Specialists. In a friend-of-the-court brief, these associations said that active state supervision was needed for physician-dominated medical boards because they have a history of unfairly limiting the scope of practice for nurses.

In response to today's ruling, AMA President Robert Wah, MD, said that his organization would work with other medical societies "to secure policy changes to reinforce long-held antitrust protections" for state medical boards.

"The AMA agrees with Justice Alito, speaking for the three dissenting justices, that today's decision 'will spawn confusion' by creating far reaching-effects on the jurisdiction of states to regulate medicine and protect patient safety," Dr. Wah said in a statement emailed to Medscape Medical News.

Ground-Breaking Lung Cancer Breath Test in Clinical Trial

Posted on Wednesday, February 18, 2015

University of Leicester and Leicester's Hospitals is set to evaluate a revolutionary device that detects lung cancer in early stages.

A clinical trial led by University of Leicester respiratory experts into a potentially ground-breaking “breath test” to detect lung cancer will get underway at the Glenfield Hospital in Leicester.

It is hoped that the LuCID (Lung Cancer Indicator Detection) program will lead to a non-invasive method of diagnosing lung cancer in the early stages. The company behind the device, Cambridge-based Owlstone Nanotech Ltd, carried out a health economic analysis and determined that detection of early-stage lung cancer could be increased from the current 14.5% to 25% by 2020, it is estimated this could save 10,000 lives and £250m of NHS money.

The device works by measuring volatile organic compounds (VOCs) at low concentrations in a patient's breath and offers a cheaper and smaller alternative to existing detection technologies.

Supported by the University of Leicester's enterprise and business development team and Leicester's Hospitals, Owlstone was awarded £1m by the NHS Small Business Research Initiative (SBRI) towards the second phase of the LuCID project -- the clinical trials. The aim is to further evaluate Owlstone's GC-FAIMS (Gas Chromatography -- Field Asymmetric Ion Mobility Spectrometry) sensor in a rapid access lung cancer clinic at Glenfield Hospital, Leicester starting later this year. If successful, the project will pave the way to evaluate the technology in GPs' surgeries and other hospitals.

Billy Boyle, co-founder of Owlstone, said: "If you could change only one thing in the fight against cancer, it would be to detect the disease earlier where existing treatments are already proven to save lives. FAIMS technology has the potential to bring a quick and easy-to-use breath test to a GP's office. Our team will not rest until we help stop the daily devastation that cancer brings to patients and their families."

The clinical study is being led by Dr Salman Siddiqui, a clinical senior lecturer and adult chest physician at the University of Leicester and Glenfield Hospital with results of the trial expected in early 2016.

The study will be delivered by a number of key members of the lung cancer clinical team including senior lung cancer clinician, Dr Jonathan Bennett.

Dr Siddiqui added: "Lung cancer has one of the lowest 5-year survival rates of all cancers, however early diagnosis can greatly improve a patient's prognosis. Current diagnostic procedures such as a chest X-ray, CT scan and bronchoscopy are costly and not without risks so the benefits of a non-invasive, cheaper alternative are clear.

"This project will seek to identify and evaluate biomarkers in order to improve the accuracy and reliability of breath diagnostic methods. We will also be aiming to establish FAIMS as a faster, less expensive and more portable alternative to gas chromatography-mass spectrometry (GC-MS) for breath diagnosis applications."

New Research Shows Possibility of Cure for HPV Positive Throat Cancer Patients

Posted on Friday, February 13, 2015

Patients with cancer of the throat caused by the Human Papilloma virus (HPV+) have a better prognosis than those who are negative for the virus (HPV-). Now, for the first time, researchers have shown with convincing evidence that a group of patients with HPV+ cancer of the oropharynx (the part of the throat located behind the mouth, that makes up the region of the tonsils and the back part of the tongue where it connects to the swallowing part of the throat), can be cured in some cases even after disease has spread to distant organs in the body, like the lungs.

Dr Sophie Huang, Assistant Professor in the Department of Radiation Oncology, Princess Margaret Cancer Centre, University of Toronto, Canada, will tell the 5th International Conference on Innovative Approaches in Head and Neck Oncology (ICHNO) today (Friday) that her research has shown that, following intensive treatment, certain patients with HPV+ oropharyngeal cancer (OPC) and distant metastases (tumours appearing in an organ not directly related to the primary cancer site) can survive for more than two years without further evidence of disease. Such cancers are usually considered to be incurable, and the goal of treatment is usually limited to symptom control. "Our research, the largest study to date to explore survival predictors for metastatic HPV+ and HPV- oropharyngeal cancer patients, has shown that cure is a realistic goal in those patients with oligometastasis -- metastases involving five or fewer lesions in one distant organ," she will say.

Dr Huang and colleagues identified 934 patients with HPV+ OPC out of the 1238 OPC patients who had been treated at the Princess Margaret Cancer Centre between 2000 and 2011. Distant metastases were detected in 15% of these patients; 88 in the HPV+ group and 54 in those with HPV- disease. Oligometastasis was present in 24 HPV+ patients with distant metastases in a single organ.

The researchers found two types of distinct distant metastases in HPV(+) patients: "explosive" and "indolent" metastases. The explosive type metastasis, where more than ten lesions in one organ appear quickly in a short period (within three months of appearance of the first lesion), was present in 55% of the HPV+ group, as opposed to none in those who were HPV-. In both HPV+ and HPV- groups, lung was the most common metastatic site. The indolent type of metastases grow and spread at a much slower pace, most often manifesting as oligometastasis. This occurred in 24% of the HPV+ cases with metastases in a single organ as opposed to 26% of those who had HPV- cancer.

"In the HPV+ group of patients with oligometastases, when they were given definitive local treatment aimed at disease control -- for example, a high radiation dose or surgical removal of the metastatic lesion, as opposed to a less aggressive treatment used to control symptoms -there was a long term disease-free period, suggesting that some may be cured," Dr Huang will say. "In the HPV+ group with oligometases 25% were still alive after three years, whereas the percentage in the HPV- group was 15%."

The survival advantage in HPV+ OPC patients is due to a number of factors, the researchers say. The cancer is more sensitive to radiotherapy and chemotherapy; the patients tend to be younger (an average age of 55 at diagnosis as opposed to 65) with fewer other health problems, including those caused by smoking-related illness, and this enables them to receive the more aggressive treatment necessary to eradicate metastatic disease.

The percentage of HPV positive to negative OPC cancers varies globally, depending on a number of factors, including the prevalence of smoking and the practice of oral sex. Overall the incidence of HPV+ throat cancers has increased over the past 20 years in developed countries, such as US, Canada, Japan, Australia, and some European countries. [1]

"This research has shown that metastatic HPV+ OPC patients who receive active treatment can survive considerably longer than those who did not receive treatment. One of the reasons patients with metastatic disease do not receive aggressive treatment is due to the physician and patient's perception that this is an incurable state. We hope that these results will motivate researchers to optimise management strategies for these patients. This will not only help to produce a better quality of life and a return to work for them, but also reduce the cost to healthcare systems," Dr Huang will say.

"We also hope that our study may trigger research to explore cost-effective methods for the early detection of metastases. Optimising and tailoring surveillance strategies for HPV+ patients are also important. For example, our research has shown that the surveillance period should be longer than the traditional two-year window, due to the possibility of later onset of metastases. Selecting the appropriate imaging method in order to detect asymptomatic oligometastasis (e.g. ultrasound for the early detection of liver metastasis) may allow salvage treatment of some patients before the cancer progresses. Finally, we hope that it will help clinicians identify patients who are best able to benefit from aggressive treatment, such as metastasectomy (surgical removal of the metastases) or stereotactic radiotherapy (highly focused high dose radiotherapy to small regions)," Dr Huang will say.

Whether it is possible to identify which patients at initial presentation are at high risk of developing distant metastasis, and which type of distant metastasis will subsequently develop are other important questions for future studies, say the researchers. "We know there is a degree of correlation between the initial stage and the risk of distant metastasis, but we did not find a strong relationship between this stage and the type of metastasis. The intensity of cigarette smoking in the years prior to the time of diagnosis is a possible factor. Being able to identify such relationships could be a huge help in deciding appropriate treatment at an early stage," Dr Huang will say.

Although head and neck cancer is the sixth most common type of cancer worldwide, awareness of it is low, and hence the majority of diagnoses are not made until the disease is in an advanced stage, resulting in limited treatment choices and hence a reduction in the chance of survival.

Professor Jean Bourhis, co-chair of the conference scientific committee, said: This important piece of research adds substantially to what we know about the role and the importance of the Human Papilloma Virus (HPV) in oropharyngeal cancers and gives real hope of improvement in both diagnosis and treatment to those who are affected by the condition."

New Findings Could Revolutionize Dogma on Bone Formation in Temporomandibular Joint

Posted on Thursday, February 12, 2015

February 11, 2015 – Findings from researchers at Texas A&M University Baylor College of Dentistry could prove to upend previous dogma on bone formation in the temporomandibular joint.

The current school of thought on bone formation in the mandibular condyle, the rounded knob where the mandible and upper jaw meet, is that cartilage cells—called chondrocytes—must form and then experience cell death before bone cells can form. Preliminary findings from the lab of Dr. Jerry Feng, professor in the department of biomedical sciences, show this may not be the case. Bone marrow cells may not be the only ones that build bone.

“The chondrocytes do not die. They transform into bone,” says Feng. “This is the most exciting part. That’s a big switch. People in this field never thought about such a mechanism.”

This month, Feng’s team submitted a proposal to the National Institutes of Health – National Institute of Dental and Craniofacial Research to secure more than $1.8 million in grant funding to further evaluate how this transformation of cartilage into bone takes place.

Cell lineage tracing on a transgenic mouse model lies at the crux of their hypothesis. In confocal microscopic images, cells tagged with reporter genes reveal the merging of bone and cartilage proteins seen in representative shades of red and green, one for each type of protein. Several published articles, including one in the Journal of Dental Researchin fall 2014, bolster the proposal.

“The idea is that the cell lineage tracing enables you to follow cartilage cells and see where they end up during growth,” says Dr. Robert Hinton, Regents professor emeritus. “You would expect the condylar cartilage cells under the normal theory to end up dying off, but it appears that a number of them are turning into bone cells or potentially forming the walls of blood vessels.”

If the 5-year grant is funded, TAMBCD researchers will further study the role of a gene known as BMPR1A in mediating Osterix, a gene vital to bone mineralization. They will do this by separately removing, or “knocking out” BMPR1A in one control group of models and Osterix in another to gauge the impact on cartilage and bone formation.

Hinton has worked with Feng on this research and says the potential for transmitting this cutting-edge research to students is tantalizing, as it creates unique research opportunities for students.

“This is stuff that is not in textbooks right now that can be brought into discussions about how bone is formed from cartilage during growth,” says Hinton.

Feng works on research with orthodontic residents and biomedical doctoral students, to whom he also teaches bone biology. Physiology course instruction for predoctoral students is a part of his role at the college, and a Feb. 18 seminar—focusing on the vital role of chondrocytes in the regulation of bone growth at the mandibular condyle—is also in the works.

The research stands to impact the knowledge base regarding how the temporomandibular joint grows and develops. In turn, this new information could change approaches to treating malocclusions and even have an impact on new therapies for injuries to cartilage, which, unlike bone, cannot repair itself.

“You can’t solve this problem overnight,” says Feng, “but step by step.”
