A Public Health Conundrum: Boys, Cervical Cancer and HPV Vaccines

Late last week, the US Food and Drug Administration (FDA) approved GlaxoSmithKline’s cervical cancer vaccine Cervarix for use in girls and women ages 10 to 25 and also approved Gardasil —Merck’s cervical cancer vaccine previously approved in 2006 for use in girls and women—for boys and men ages 9 to 26. For those of you who may not know, over 99% of human cervical cancers are caused by infections with cancer-causing strains of the human papilloma virus (HPV) which also causes venereal warts. Vaccination with Cervarix protects against cervical cancer by inducing immunity against HPV 16 and 18 (which cause most cervical cancers in developed nations) whereas Gardasil affords protection against HPV 16 and 18 as well as HPV 6 and 11, strains that cause venereal warts (which don’t lead to cancer).

Despite FDA’s approval to vaccinate boys with Gardasil to prevent HPV infections, the Centers for Disease Control’s Advisory Committee on Immunization Practices (ACIP)— which guides national policy on use of vaccines—decided yesterday to recommend the use of the vaccine in girls and women but didn’t fully endorse its use in males. Typically, ACIP recommendations are adopted by professional medical associations and set the standards of practice for physicians. Also, its recommendations play a major role in determining whether or not insurers and third party payors will reimburse patients who are vaccinated. The new recommendations mean, in effect, that physicians and clinics may now administer the vaccine at their discretion to boys and men ages 9 to 26, but they are not expected to offer it. In contrast, vaccination of girls and women ages 10 to 25 will be strongly recommended, readily available and reimbursable. This means that parents may consider the vaccine as an option for their sons, but some health insurers may choose not to cover the shots—an option which is sure to severely limit the numbers of boys and men who are vaccinated with Gardasil.

The ACIP committee decided not to include Gardasil immunization for boys and men on its recommended list because several members, most notably a medical economist, questioned whether vaccinating boys would be cost effective in the long run. At the heart of the debate was whether or not it was appropriate and cost-effective to vaccinate boys for a problem (venereal warts) that can be embarrassing and uncomfortable but is not life-threatening. For those of you who may not know, Gardasil immunization is expensive and requires a series of three injections that cost $130 each ($390 total).  Cervarix, which also requires a series of three injections, is planned to be offered for $385.

Last year in the United States, about 37 percent of girls ages 13 to 17 started the Gardasil vaccine series, a national immunization survey showed, and about half of them completed it. Not a great track record for a vaccine demonstrated to prevent cervical cancer and dramatically reduce the transmission of venereal warts. Nevertheless, yesterday’s decision to recommend vaccination for girls and women but not boys and men makes no sense to me from a public health perspective and it almost smacks of gender bias. Let me explain.

Like all other sexually transmitted diseases (STDs), HPV is transmitted from men to women and visa versa. Based on years of epidemiological studies, the only effective way to reduce the overall incidence of STDs is to implement strategies that prevent infections in both females and males. While boys and men can’t develop cervical cancer, they do contract venereal warts and perhaps, more importantly, can serve as carriers or reservoirs of HPV infection in the population. In other words, infected males (who may or may not show symptoms of HPV infection) still possess the potential to transmit it to sexually-active, unvaccinated girls and women. Consequently, while the incidence of HPV infections may begin to decrease among women after immunization, it will never be completely eliminated and the possibility of developing cervical cancer will continue to be a public health concern.

While the ACIP’s understanding of the transmission of STDs is tragically flawed, its willingness to publicly disclose cost effectiveness as a reason to not endorse HPV vaccination for males is even more egregious! The agency’s decision begs the question: Which is more costly; 10,000 American women developing cervical cancer each year (and countless others going for unnecessary cervical biopsies because of “bad” Pap smears) or a heads up to insurance companies that they ought to cover the costs of male HPV immunizations? 

The ACIP’s reluctance to recommend male HPV vaccination based on economic and health care cost concerns rather than on public health implications is yet another example of how broken the US healthcare system is and how drastically it needs to be reformed. Allowing 3,700 women to die each year in the US from cervical cancer when there is a safe and effective way to prevent these deaths is, in my opinion, unconscionable!

Until next time...

Good Luck and Good Job Hunting!!!!!

 

Antibiotic Resistance and Healthcare: A Telling Statistic

I have refrained from commenting on healthcare reform until now because there wasn’t much I could add to the debate. That said, while reading an article in a local paper on bacterial antibiotic resistance and how to minimize it, the author—an infectious disease doc—offered a telling statistic that identified the root problem with our current healthcare system. According to the article, 65% of the time, physicians will prescribe antibiotics to patients suffering from upper respiratory tract infections who demand them, whether or not they are warranted. In marked contrast, 12% of patients with upper respiratory tract infections who don’t ask for antibiotics receive antibiotic prescriptions. The bottom line: physicians give patients the drugs and treatment they demand because they are afraid of losing them as customers knowing full well the patients will go to another physician who will give them what they want! After all, physicians are in business and to stay in business they need to make enough money to cover their overhead and make a profit. However, over prescribing antibiotics is one of the main reasons why we are in the midst of an epidemic of infections caused by multiple drug resistant bacteria. In my opinion, business outcomes should never supersede or trump medical or public health outcomes.

Don’t get me wrong, I am an entrepreneur and believe that people with good ideas ought to be rewarded for their efforts and make as much money as they can. However, in my opinion, for profit business practices and healthcare haven’t historically worked well for the American healthcare system. Removing profit incentives from healthcare would be an important first step to begin to repair our broken healthcare system. Can anybody say public option?

Until next time...

MRSA in the News Again: Another Misleading Report

Last week, I took a group of Seattle researchers to task about issuing a press release about isolating methicillin resistant Staphylococcus aureus (MRSA) from sand samples taken from public beaches in Washington State. Their findings were neither remarkable nor news worthy and likely did more harm than good. Sadly, another article about MRSA—designed to alarm rather than inform and educate the American public—appeared in today’s Science section of the NY Times.

The article, “Ties to Pets Has Germ Jumping To and Fro” in which the word “germ” appeared several times, reports on the possible transmission of MRSA between humans and their pets, most notably dogs and cats. Much of the article focuses on the “strong link between animal to human transmission,” offers several frightening examples of serious zoonotic cases that have been recently reported and suggests that cats are eight times more likely than other pets to transmit MRSA to their owners. After reading the first part of the article, readers would rightfully believe that we are in the midst of a massive zoonotic MRSA epidemic with family pets at its epicenter.  However, on the second page of the article the author mentions an epidemiological survey study conducted by Dr. J. Scott Weese, a veterinarian from the University of Guelph in Ontario Canada which showed  that only “two to three percent of pets carry MRSA on their fur or skin or in their saliva.” Further, the study suggests that healthy animals that are transiently colonized by MRSA eliminate them “in a manner of weeks.” Compare the 2 to 3 per cent carrier rate in pets with an almost 70% human carriage rate of MRSA. While I am a PhD-trained infectious disease microbiologist, I don’t think it requires a PhD to quickly realize that pets really aren’t a major source or cause of MRSA infections for humans. That said, raising awareness among veterinarians about MRSA might aid in the development of appropriate disease surveillance, diagnostic testing, andinfection control to lessen the impact of MRSA on smallanimals.

I have no doubt that many people will look at and possibly treat their pets differently after reading the Times article. Further, many will unnecessarily spend money to have their pets tested for the presence or absence of MRSA. While informing the American public that pets (like humans) might unknowingly transmit MRSA is a good thing, turning the rare transmission of MRSA from animals to humans into a major epidemiological brou-ha-ha is misleading, scientifically disingenuous and reckless. Good journalism should inform and educate, not alarm and frighten people by presenting misleading and wrong-headed information. 

Until next time....

Good Luck and Good petting your pets (it will do more good than harm)

Much Adieu about Nothing: MRSA Found at Public Beaches in Washington State

The 2009 Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) is currently taking place in San Francisco. For those of you who may not know ICAAC, is an annual meeting mainly attended by infectious disease physicians and researchers where the latest and most cutting edge research on infectious agents is reported. Things must have been a little slow at this year’s meeting (except for H1N1 of course) which led the newswires to pick up a story about the isolation of methicillin resistant Staphylococcus aureus  (MRSA) at public beaches in Washington State. While MRSA infections are certainly a public health concern, particularly among infants, older adults and immunocompromised individuals finding MRSA at public beaches isn’t particularly surprising nor newsworthy.

S. aureus is an opportunistic pathogen that isn't particularly virulent and is incapable of causing disease unless it is accidentally introduced into a wound, surgical incision or similar environment. In humans, the bacterium colonizes mainly the nasal passages, but it may be regularly found in most other anatomical locales, including the skin, oral cavity and gastrointestinal tract. Epidemiological studies have demonstrated that over 70% of people transiently carry S. aureus in their nasal passages at one time or another in their lives. This means that S. aureus is very common and ubiquitous in human populations. Consequently, I wasn’t surprised when I learned that Seattle researchers had isolated S. aureus at public beaches in Washington State. Nor was I shocked to learn that some of the isolates were MRSA strains!  After all, the incidence of methicillin-resistant S. aureus has been steadily increasing in the US and elsewhere for the past 20 years. And, healthy people who carry MRSA (and regularly shed it from their bodies) do like to go to beach and lay in the sand when the weather is warm. That said, I would have flabbergasted if the researchers didn't isolate MRSA from the beach sand samples that they surveyed. As an aside, I want to let my readers know that I isolated S. aureus from a soil sample while an undergraduate microbiology  major at Cornell University. Finally, while some MRSA infections can be fatal, those that are diagnosed correctly and early are usually easy to eliminate with conventional antibiotic regimens.

Because the work mentioned in the ICAAC press release hasn’t been published, it is  difficult to evaluate the results and implications of the study's findings.  Nevertheless, I don’t think it was prudent for the scientists who conducted the research to issue a press release about finding MRSA at public beaches—especially when the American public is already jittery about infectious agents like H1N1. If the authors’ intent was to make a big splash (pun intended) by mentioning the “dreaded MRSA” in their press release, they were successful—the story is all over the news. However, in my opinion, we are obliged as scientists to accurately inform the lay public about important scientific and public health issues—not play into its worse fears and misconceptions about them.

Until next time...

Swine Flu Pandemic: Many Questions and Few Answers

Vincent Racaniello, an intrepid virologist and BioCrowd co-founder, has been keeping folks up to date on the swine flu outbreak on his blog. Today, Vincent wrote: “There are now 257 laboratory confirmed cases, with 7 deaths, in 11 countries. In the US there are 109 cases  in 11 states. There are many more suspected cases; together the statistics indicate widespread dissemination of the new H1N1 influenza virus. I no longer doubt that this is the next pandemic strain. WHO will probably soon raise the level of influenza pandemic alert from phase 5 to phase 6. Important questions include whether spread will continue in the northern hemisphere through the summer, or stop very soon, as is the case with most influenza virus outbreaks. Unfortunately the southern hemisphere seems in for an extended flu season. Will antivirals be useful in reducing morbidity and mortality? Will the virus returns to the north in a more virulent form in the fall? Can a vaccine be prepared in time?”

 For answers to these questions and others, please visit the Virology Blog or join BioCrowd to chat with Vincent. Check his virology blog for the most up-to-date swine flu information.

Word on the Street: Novartis May Purchase Cubist for $1.6 billion

Rumors are rife that Novartis is going to purchase Lexington, MA-based Cubist for $1.6 billion. Wall Street analysts are speculating that Novartis may announce the deal as early as Monday.

Cubist manufactures Cubicin (daptomycin), one of only a handful of new antibiotics brought to market in the past 20 years that is effective against many infections caused by Gram-positive bacteria, most notably methicillin-resistant Staphylococcus aureus (MRSA). The company is developing new lipopeptide antibiotics similar to Cubicin and also has an active anti-viral drug discovery program.

Over the past 10 years, big pharma companies largely abandoned antibiotic research and placed all discovery efforts in the hands of only a few smaller public companies and startups. Cubist is the only independent biopharmaceutical company that successfully brought a new antibiotic to market. 

Novartis’ possible acquisition of Cubist signals, that at least one major pharmaceutical company sees opportunities and upside in the antibiotic drug discovery market. Several years ago, Pfizer acquired another antibiotic discovery company, Vicuron (formerly Versicor) but to date the acquisition has not yielded any new antibiotics. While Novartis’ acquisition of Cubist is yet another sign of consolidation that is taking place in the life sciences sector, it may bolster new efforts in the antibacterial drug discovery area. Unlike Cubist, Novartis has enough money and marketing muscle to increase Cubin sales and develop some of the exciting new molecular entities in Cubist’s drug development pipeline.

Until next time…..

Methicillin Resistant Staphylococcus aureus: A Growing Link between MRSA Infections and Pigs

That methicillin resistant Staphylococcus aureus (MRSA) is in the news again is not surprising. However, to my knowledge, Nicholas Kristof‘s article in today’s New York Times may be the first Op-Ed piece written by a non-scientist about the growing threat and seriousness of MRSA infections. Mr. Kristof apparently became aware of MRSA when he was contacted by Tom Anderson, MD, a Camden, Indiana physician who was experiencing “phenomenal levels of MRSA infections" in his community.

Beginning in the early 1990s, Dr Anderson noticed a rapidly rising incidence in the number of community acquired skin infections caused by MRSA among his patients. Most of Dr Anderson’s patients were swine farmers—the predominant industry in Camden. At first puzzled by the growing incidences of MRSA outbreaks, Dr. Anderson began to suspect that his patient’s pigs may be the source of growing number of cases of MRSA skin infections. He was reluctant to alert public health officials about his suspicions because any hint livestock-related health issues might jeopardize the livelihood of many of his neighbors and friends. By last fall, however, Camden’s MRSA epidemic had grown so large that Dr. Anderson could no longer remain silent. Rather than alert the authorities himself, he decided to invite Mr. Kristof, an investigative reporter, to visit him in Camden and break the story. Unfortunately, before Mr. Kristof could visit, Dr. Anderson died abruptly at age 54. There was no autopsy, but a blood test suggested he may have died from a heart attack or aneurysm. And—this is where the story gets interesting—a recent Dutch study has linked porcine MRSA isolates to a case of human endocarditis. Dr. Anderson had himself suffered at least three bouts of MRSA infections.

In another Dutch study conducted in 2004, MRSA strain ST398 (which caused the endocarditis in the more recent study) was isolated from three family members, three farm workers and 8 of 10 pigs from a single farm. Since then, strain ST398 has spread rapidly through the Netherlands — especially in swine-producing areas— and pig farmers there are 760 times more likely than the general population to carry MRSA. More recently, a study conducted by public health officials in Ontario, Canada showed that 20% of pig farmers were colonized by strains of MRSA genetically identical to those isolated from European pigs. Finally, a 2008 study conducted in Iowa, reported that strain ST398 was isolated from 45 percent of pig farmers and 49 percent of hogs that were tested. Together, these studies suggest that colonization of swine by MRSA and pig farmers is very common and that swine (and possibly other agricultural animals) could become an important reservoir for strains of MRSA.

While not conclusive, most infectious diseases experts believe that the emergence of MRSA and antibiotic resistant bacteria can be directly linked to the widespread and rampant use of antibiotics as growth enhancers in livestock feed. Despite the alarming emergence of multiple antibiotic resistance bacteria, livestock producers in the US and elsewhere continue to add antibiotics to livestock feeds. This led Mr. Kristof to lament that “we as a nation have moved to a model of agriculture that produces cheap bacon but risks the health of all of us.” Not surprisingly, as is frequently the case, big business has chosen to place profits before the health and safety of society.

Until next time...

 

Good Luck and Good Reading (look for Mr. Kristof’s Sunday column on the emergence of antibiotic resistant "superbugs")

Another Antibiotic Discovery And Development Company Is Downsizing

Targanta Therapeutics, a Cambridge, MA-based biopharmaceutical company, announced that it will lay off 85 of its 115 employees or almost 75% of its workforce. The news follows the FDA’s rejection of its application for oritavancin, an antibiotic it is developing to treat infections caused by methicillin-resistant Staphylococcus aureus (MRSA) and other antibiotic resistant bacteria. The agency wants Targanta to conduct another Phase III clinical trial to further assess of oritavancin’s safety and efficacy.

The company estimates that the new clinical trial will cost about $20 million. Targanta CEO Mark Leuchtenberger said “We are no longer a pre-commercial company. We are back to being a Phase three company, and that requires us to right-size and to streamline our operations.”

Things are not going well for companies in the antibacterial drug discovery and development space. Late last month, FDA rejected Swiss-based Arpida’s NDA for iclaprim an antibiotic it was developing to treat complicated skin and soft infections caused by MRSA. Shortly after receiving the news, Arpida layed off roughly 72% of its employees and is down to about 30 employees like Targanta.

It is unfortunate that big pharma decided to abandon antibacterial discovery and development research about eight years ago. Consequently, development of  new, much-needed antibiotics has been relegated to financially-strapped, small biopharmaceutical companies whose likelihood of success is questionable.

Until next time…

FDA Delays Approval of Ceftobiprole to treat MRSA

U.S. regulators have delayed a decision on approval of an antibiotic from Johnson & Johnson and Basilea saying they need further audits of clinical sites, the two companies said on Wednesday.

Ceftobiprole, a broad-based spectrum antibiotic targeted mainly against infections caused by methicillin-resistant Staphylococcus aureus (MRSA), is Basilea's lead product and the news hit the Swiss biotech shares, which plummeted 27 percent.

In a so-called complete response letter on the drug's approval application, for complicated skin and skin structure infections, the Food and Drug Administration (FDA) said it was unable to review the clinical data submitted with the NDA until issues of data integrity had been resolved. The FDA has asked J&J to conduct additional audit work of clinical investigator sites and to address specific questions related to site monitoring."

Ceftobiprole is approved in Canada and Switzerland and has been recommended for approval in the European Union. A new application in the United States is planned within a year.

Late last week, FDA rejected an NDA for another antibiotic, iclaprim, being developed by Arpida, another Swiss company. It has been a bad two weeks at FDA for approval of new antibiotics—drugs that we desperately need.

Until next time….

FDA Advisory Panel Rejects another NDA for a New Antibiotic

A Food and Drug Administration (FDA) advisory panel Thursday rejected a proposed antibiotic by Arpida Ltd. (ARPN.EB) to treat serious skin infections, a Food and Drug Administration spokeswoman said. The rejection was expected because results from Phase III clinical trials showed that patients taking iclaprim (a trimethoprim-like antibiotic) had lower cure rates than Pfizer's Zyvox (linezolid) which was used as a comparator antibiotic in the studies.

The panel voted 17 to 2 against a question that asked whether the data presented demonstrated the safety and effectiveness of iclaprim for the treatment of skin infections. Although FDA isn’t required to follow the advice offered by its advisory panels, the agency typical follows the panels’ recommendations. This means that it is unlikely that FDA will approve iclaprim to treat complicated skin and soft structure infections (cSSIs).

This is bad news for Arpida Ltd, a small, Swiss biopharmaceutical company and Americans with cSSIs infections that are caused by  multiple drug resistant bacteria.

Until next time…

Another New Antibiotic Bites the Dust (for now)

Pfizer announced today that it would withdraw marketing application being considered at FDA and the European Medicines Agency (EMEA) for Dalbavancin an antibiotic it was developing for complicated skin infections caused by bacteria including methicillin-resistant Staphylococcus aureus (MRSA).

Pfizer acquired Dalbavancin after it purchased California-based Vicuron Pharmaceuticals for $1.9 billion in 2005. At that time, Vicuron had filed an NDA with FDA and had expected approval for the novel antibiotic. Instead, after acquiring Vicuron, Pfizer received an approvable letter from FDA that requested additional studies before the agency would approve the drug. Based on the agency’s comments, Pfizer decided to withdraw the original US and European applications filed by Vicuron and conduct addition Phase III clinical trials for the complicated skin and soft tissue infection and pediatric indications. I suspect that results from these trials will determine whether Pfizer files new applications with FDA and EMEA for Dalbavancin.

For those of you who may not know, Vicuron Pharmaceuticals was formerly called Versicor, a company founded by Eric Gordon, Mickey Gorman and others. In 1996, I was recruited to interview for a Vice President of Biology position at the company.  At that time, Versicor had about 15 employees — Eric was CEO and Mickey was a consultant.  Although Eric, Mickey and I became fast friends, I didn’t get the job (they never hired anybody for the position). 

Both Eric and Mickey left Versicor a couple of years later. Eric went on to start Sunesis, a very successful Bay area oncology company and Mickey retired to his home in Key West, FL. From time to time, I would run into Eric at BIO meetings and Mickey and I would meet up at my all time favorite Vietnamese restaurant (Hy Vong) in Little Havana in Miami, FL. Eric has since retired after 30 years in the pharma/biotech biz and Mickey unfortunately passed away from cancer in the early 2000s.

 

After meeting Eric and Mickey, I knew that Versicor would be a success one day—the $1.9 billion that Pfizer paid for Vicuron tends to validate that notion. While I didn’t benefit financially from Versicor, I was lucky and fortunate to meet two, really smart, fascinating and genuine individuals who helped me to establish my credibility in the biopharmaceutical industry.  As the saying goes “Money isn’t everything!”

Some Tips to Reduce the Incidence of Antibiotic-Resistant Bacteria

A friend of mine accidentally gashed his leg on an open dishwasher door and thought nothing of it for several weeks until he noticed that the wound wasn’t healing and it hurt really badly. He eventually went to the emergency room at a local, where the ER docs cultured the wound and sent him home with a prescription for oral antibiotics. The antibiotics stopped working several days later and he wound up in another local hospital–this time he was admitted and the spent the next 5 days on a variety of intravenous antibiotics. Despite the treatment (they could not find the right antibiotic combination at first because  they never recultured the wound) his leg turned black from his ankle to his knee and they almost had to amputate. He is back at home now and will be treated with a regimen of iv antibiotics for the next 6 weeks or so. I talked with him last week and I learned that his leg wound is still not completely healed and the infectious disease docs are worried!

My friend almost lost his leg because of a lack of understanding about bacterial infections and antibiotic resistant bacteria and— unfortunately— because of substandard wound care treatment. With this in mind, I am posting what I think are useful tips (from the June issue of the Mayo Clinic Women’s Health Source) about how to prevent, manage and treat wound infections to minimize the emergence and spread of multiple, antibiotic- resistant bacteria.

  • Wash your hands: This simple procedure, done properly, remains the best defense. Carry alcohol-based hand sanitizers for times when hand washing isn’t possible.
  • Keep personal items personal: Don’t share towels, soap, sheets, razors, clothing or athletic equipment.
  • Sanitize linens: If you have a cut or abrasion, wash towels and sheets with hot water and added bleach. Wash gym and athletic clothes after each use.
  • Get infections tested: If an infection requires treatment, ask your care provider to take a culture to confirm what bacteria are present before you are given an antibiotic. (Editor’s note: Unfortunately, this is no longer standard practice—most infections are treated empirically which is partly responsible for the increasing frequency of antibiotic resistant bacteria.) If you test positive for a Staphylococcus (Staph) infection, ask that a culture be tested specifically for MRSA in case you need a special antibiotic.
  • Use antibiotics appropriately: When you take antibiotics, take all doses even when you start feeling better. Don’t demand antibiotics for viral illnesses; antibiotics don’t work with viruses. Taking too many antibiotics over time could become a detriment because the medication’s effectiveness can be compromised by overuse.
  • Use antibacterial products sparingly: Antibacterial soaps and cleaning products probably don’t prevent infections at home and may make these products less effective in hospitals.
  • Take precautions in the hospital: Ask all hospital staff and visitors to wash their hands or use an alcohol-based hand sanitizer before touching you. Ask care providers to wipe stethoscopes and other equipment with alcohol. Don’t set food or utensils directly on tables or beds. Make sure that intravenous tubes and catheters are inserted under sterile conditions.

I hope that these tips will help to keep you out of the hospital with potentially life-threatening, antibiotic resistant bacterial wound infections!

The Nose Knows-Antibiotic Treatment May Not Help Sinus Infections

Sinus infections are diagnosed in about 31 million Americans each year and are among the most common reasons for doctor visits. The infections affect the air spaces (sinuses) around the nose and in the lower forehead. Inflammation and excess mucous can cause nose congestion, headaches and eye and face pain. Causes include bacteria, viruses, fungal infections and allergies.

A study published in the December issue of the Journal of the American Medical Association (JAMA) showed that patients with sinus infections treated with antibiotics did not get better more quickly than those treated with placebo, And, that most sinus infections would resolve themselves over time without treatment. The lack of effectiveness of antibiotic treatment could be explained by the inability of many antibiotics to reach the site of infection in the sinuses. Also, it is important to point out, that antibiotic treatment is ONLY EFFECTIVE when treating bacterial infections; not those caused by viruses or fungi. To that end, infectious disease experts issued guidelines in 2001 advising against using antibiotics for most sinus infections in otherwise healthy people, blaming overuse for contributing to the growing problem of antibiotic resistance.

Critics of the study questioned whether all the patients in the study had true bacterial sinus infections. Although patients were recruited to the study by family doctors, the results were based on patients' self-reported symptoms rather than medical exams that confirmed actual cases of sinus infections. So it goes….

BTW, recent studies suggest that yellowish or greenish mucous doesn't always mean the infections are bacterial–another urban legend bites the dust.

Until next time….
