Using a lab-grown trachea, surgeons conduct the world’s first synthetic organ transplant

Source: www.popsci.com Author: Clay Dillow Surgeons working at Karolinska University Hospital in Sweden have taken a huge step forward for regenerative medicine by successfully executing the world’s first synthetic organ transplant. The donor-less transplant saved the life of a 36-year-old cancer patient, who is doing well now after having received a new windpipe grown from his own stem cells. This story is about as international as it gets: The Eritrean patient, Andemariam Teklesenbet Beyene, was pursuing his doctorate in geology in Iceland when his trachea was consumed by an inoperable tumor that grew so bad that it was actually blocking his breathing. So 3-D scans of his windpipe were sent to scientists at University College London, which crafted a glass scaffold that was a perfect match for Beyene’s trachea and two main bronchi. The scaffold was in turn was sent to Sweden, where it was soaked in stem cells from Beyene’s own bone marrow. The stem cells took hold and within just two days had filled the scaffold, creating a new trachea that is, biologically speaking, Beyene’s own tissue. A 12-hour operation by an Italian surgeon specializing in trachea operations removed Beyene’s windpipe and all signs of the cancer and then replaced it with the new, lab-grown organ. That was a month ago. Today, Beyene is recovering well. Because the organ was grown from his own cells, there is no risk of his body rejecting it and no need for the harsh regimen of anti-rejection drugs that usually go hand [...]

Artificial nose could hold the key in detecting head and neck cancer

Source: www.healthcanal.com Author: staff An artificial nose could hold the key in detecting head-and-neck (HNC), according to scientists. The results1 have shown the man-made Nanoscale Artificial Nose (NA-NOSE), developed at the Israel Institute of Technology2, can effectively distinguish between head-and-neck cancer patients, lung cancer patients and those free of oral cancer simply by sampling a breath test. Head-and-neck cancer is the eighth most common curable cancer worldwide and is often diagnosed late due to a lack of successful screening methods. Research suggests overall cure is achieved in less than one in two patients, while sufferers often develop a second primary tumour that can affect the entire aero-digestive tract, making lifelong follow-up necessary. As this appears to be the first study of its kind, Chief Executive of the British Dental Health Foundation, Dr Nigel Carter, believes more needs to be done in order to validate this promising breakthrough in the battle against oral cancer. Dr Carter said: "The discovery of an effective screening method for a cancer which kills one person every five hours in the UK using a relatively simple method represents excellent progress. However, the Foundation urges greater investigation into the feasibility of using such a device on a larger scale. "The Foundation runs Mouth Cancer Action throughout November under the tagline ‘If in doubt, get checked out'. The campaign aims to raise awareness of mouth cancer among the public and encourage people to visit their dentist or doctor for regular check-ups. If a breath test could hold the [...]

Study identifies patients best suited to second round of head-and-neck treatment

Source: http://www.oncologynurseadvisor.com/ Author: Delicia Honen Yard A small group of patients with recurrent or second primary head and neck cancer achieved long-term cure after undergoing concomitant chemotherapy with reirradiation. However, the associated risk of severe toxicity demonstrated that only carefully selected patients should undergo treatment readministration. Joseph Salama, MD, formerly with the University of Chicago (Illinois), and colleagues analyzed data from 166 patients with head and neck cancer who had received a first round of radiation followed by a second round plus chemotherapy because their cancer recurred or because they developed a new tumor. After a median follow-up of 53 months among surviving patients, median overall survival was 10.3 months. The 2-year rates for overall survival, disease-free survival, locoregional control, and freedom from distant metastasis were 24.8%, 19.9%, 50.7%, and 61.4%, respectively. Despite yielding a 2-year cure rate of nearly a quarter of the subjects, the second course of treatment was highly toxic: 33 participants (19.9%) died of treatment-related toxicity, and some lost the ability to speak or swallow. The investigators found that certain patients benefited from the second treatment over others: Those who were cancer-free for a longer period of time, did not have chemotherapy with their first course of radiation, were treated with a higher dose of radiation in their second round, and had surgical resection or debulking prior to the second course of radiation were more likely to be cured at 2 years than those who had none or only some of these features. “This can help doctors determine [...]

Palifermin reduces severe mucositis in head and neck cancer

Source: http://www.medscape.com/ Author: Janis C. Kelly Palifermin (Kepivance), which is currently approved for preventing mucositis associated with total-body irradiation and stem-cell transplantation in hematologic malignancies, also prevents oral mucositis in patients with head and neck cancer undergoing radiation and chemotherapy, according to 2 randomized trials published online June 13 in the Journal of Clinical Oncology. Michael Henke, MD, who led both studies, told Medscape Medical News that "this shows for the first time that radiation-induced mucositis can be ameliorated — and this in a phase 2/3 design!" Dr. Henke is from the Department of Radiation Oncology at University Clinic in Freiburg, Germany. The multicenter studies included researchers from Austria, France, Germany, Hungary, Italy, Poland, Spain, the United Kingdom, and the United States. The first study was a double-blind randomized placebo-controlled trial of 186 patients with stage II to IVB carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx. Treatment included radiation, 60 or 66 Gy, after complete or incomplete resection, delivered at 2 Gy per fraction and 5 fractions per week. Treatment also included cisplatin 100 mg/m2 on days 1 and 22 (and on day 43 with incomplete resection). Patients were randomized to weekly palifermin 120 μg/kg or placebo from 3 days before and throughout radiochemotherapy. The primary end point was the incidence of severe oral mucositis (World Health Organization [WHO] grades 3 to 4). Palifermin reduced oral mucositis incidence to 51% (41 of 92), compared with 67% (63 of 94) with placebo (P = .027), shortened median mucositis from [...]

New labels may not go far enough

Source: www.denverpost.com Author: Rhonda Hackett How far would you go to stop a killer? Smoking continues to kill more Americans every year than alcohol, AIDS, car accidents, illegal drugs, murders and suicides combined. Tobacco use remains the leading preventable cause of death and the single greatest driver of health-care costs in Colorado. Despite concerted efforts over recent years to educate people about the dangers of tobacco use, 46.6 million American adults smoke, while kids alone are responsible for roughly $2 billion in annual cigarette sales revenues. More than 400,000 people die every year from tobacco use (4,300 in Colorado), while an additional 50,000 adults die as a result of second-hand smoke exposure. More than 8 million Americans currently suffer from tobacco- caused illnesses, resulting in an estimated $96 billion in public and private health care expenditures each year. In Colorado, the tab is about $1.3 billion per year. Simply put, tobacco is the single most lethal and costly legal commodity available in America today. The U.S. Food and Drug Administration has now followed the lead of other developed nations by requiring cigarette packages carry graphic warning labels. FDA Commissioner Margaret Hamburg said at a White House briefing, "We want kids to understand smoking is gross - not cool - and there's really nothing pretty about having mouth cancer." Critics of the warning labels cite the fact that smoking is a legal activity and as such products associated with it should not be subject to government mandate discouraging use. The Institute [...]

Late diagnoses may have caused U.K. oral cancer deaths

Source: http://www.drbicuspid.com/ Author: DrBicuspid Staff Late diagnoses and referrals could have resulted in the deaths of several oral cancer patients at a dental hospital in Belfast, U.K., according to a story in the Belfast Telegraph. A report found the Belfast Health Trust guilty of "serious deficiencies" after 15 oral cancer patients at the Royal Dental Hospital received late diagnoses and referrals. Health Minister Edwin Poots said that four of the 15 could have died as a consequence. Poots also disclosed that five senior directors of the trust received pay increases of between 5% and 10%, which cannot now be legally retrieved, involving a total of 26,000 pounds ($41,793 U.S). Also, government officials were told there may be "potentially material shortcomings" over the procurement of a security services contract at the Belvoir Park Hospital site in south Belfast. The problems were attributed to excessive workloads, exacerbated by the lack of an adequate secretarial and administrative support system. In February, it was revealed that two years ago the trust launched a major review of 3,000 clinical records belonging to dentistry patients in Northern Ireland.

Hypersensitivity Reactions to Erbitux Caused by Tick Bites.

Source: Gastroenterology & Endoscopy News Hypersensitivity reactions to cetuximab (Erbitux, ImClone Systems/Bristol-Myers Squibb), a monoclonal antibody approved for use in colorectal cancer, are not caused by the drug itself but by preexisting immunoglobulin E (IgE) antibodies that may result from tick bites, researchers have found. Cetuximab, like other monoclonal antibodies, is generally associated with a low rate of severe anaphylactic reactions (3%), but reports of such reactions to cetuximab have recently increased in southeastern states, including Tennessee and North Carolina. Researchers found IgE antibodies in pretreatment samples of 68% of patients allergic to cetuximab that were specific for galactose-α-1,3-galactose, an oligosaccharide present on the Fab portion of the cetuximab heavy chain. The authors noted that rates of anaphylactic reaction may be lower with other monoclonal antibodies because cetuximab is produced in the mouse cell line SP2/0, which expresses this oligosaccharide, whereas most other monoclonal antibodies are produced in a Chinese hamster ovary cell line that does not express this molecule. Theories to explain the increased hypersensitivity of patients in the Southeast initially centered on exposure to worms, such as roundworms or tapeworms. However, researchers now believe the true culprit may be ticks, whose bites have resulted in the development of this type of IgE antibody. Pretreatment samples were obtained from 76 people treated with cetuximab at centers mainly in Tennessee, Arkansas and North Carolina; the control group included 72 people in Tennessee, 49 patients with cancer in northern California and 341 women in Boston. Of the patients on cetuximab, 25 [...]

The Value of Vaccines

Source: Medscape.com Vaccines Decrease Rate of Bacterial Meningitis A recent, retrospective study revealed that the incidence of bacterial meningitis decreased by 31% over 10 years, likely the result of vaccinations (Thigpen et al. 2011). In addition, the median age of those infected increased from 30.3 to 41.9 years, evidence that vaccinating the young has protected them from infections while leaving older, unvaccinated people more vulnerable. The authors analyzed data on bacterial meningitis from 1998-1999 to 2006-2007 in 8 surveillance areas of the Emerging Infections Programs Network, which includes 17.4 million people. The 5 most common pathogens for bacterial meningitis were Haemophilus influenza type b (Hib), Streptococcus pneumonia, group B streptococcus (GBS), Listeria monocytogenes, and Neisseria meningitides. Cerebrospinal confirmation of the clinical diagnosis was required. The beneficial effect of vaccines during the surveillance period is striking. The incidence of bacterial meningitis from Haemophilus influenza decreased by 35%. For strains of bacterial meningitis from Streptococcus pneumonia included in the PCV7 vaccine, infections decreased by 92%. Conversely, rates of meningitis from group B streptococcus, for which there is no vaccine, did not change.

What Really Killed Farrah Fawcett?

Source: Empowher.com In a recent interview between CNN’s Piers Morgan and Ryan O’Neal, O’Neal claimed that the stress resulting from his family turmoil may have contributed to Farrah Fawcett’s death. He stated,“…we really don’t know what causes cancer…” When it comes to anal cancer, the disease that took Fawcett’s life in June of 2009, we certainly do know the cause. More than 90 percent of anal cancers are the result of Human Papillomavirus (HPV). This is the same virus responsible for cervical, vulvar, vaginal, penile and oral cancers. The list of cancers resulting from HPV continues to grow, with oral cancer (mainly affecting men) as the latest on the ongoing list. It has been known for quite some time, however, that HPV is responsible for anal cancer. Over the past three decades, anal cancer has risen among women by 78 percent, and it has risen among men by 160 percent. Those figures were taken from a study done in 2004 by the Fred Hutchinson Cancer Research Center in Seattle, Washington. It has been another seven years, and still, little is done to inform the public of this rapidly growing trend and the vaccine that can prevent the two most aggressive strains of HPV known to cause anal cancer. When Fawcett’s documentary regarding her diagnosis and treatment for anal cancer aired in 2009, anal cancer survivors and others with HPV watched intently. They wanted to see if there would be a public service announcement at the end of the documentary to [...]

Philip Morris sues Australia over cigarette packaging

Source: http://www.nytimes.com/ Author: Bloomberg News Philip Morris International said it had started legal action against the Australian government over the nation’s plans to allow the sale of cigarettes only in plain packages. The company filed a notice of claim against the government saying that the proposals violate terms of Australia’s Bilateral Investment Treaty with Hong Kong, according to an e-mailed statement on Monday from Philip Morris’s Asian unit. A copy of the court document was not immediately available. Australia, which has already banned the public display of tobacco products in retail outlets, wants to outlaw logos on cigarette packs and force them to be sold in plain dark-olive packaging, carrying health warnings instead of company logos. Cigarette brand names will appear on the packages in the same size and style of printing. The legislation, if passed by Parliament, would come into force in 2012. “The forced removal of trade marks and other valuable intellectual property is a clear violation of the terms of the bilateral investment treaty between Australia and Hong Kong,” Anne Edwards, a spokeswoman for Philip Morris Asia, said in the statement. “We believe we have a very strong legal case and will be seeking significant financial compensation for the damage to our business.” The government raised tobacco taxes by 25 percent last year as it sought to curb smoking, which is the nation’s largest single preventable cause of death, according to the nation’s health minister, Nicola Roxon. “We don’t believe that taking that action is in breach [...]
