Rabies

Monday, June 30th, 2008


Does anyone remember the old old Disney movie “Old Yeller”? I was just a kid when I watched this tear jerker, but what I remember most about it was that Old Yeller got rabies and died. Rabies was one of the first serious diseases I ever learned about as a kid. My first medical word was “hydrophobia”.

In the U.S. and Canada, rabies is really rare. In Canada, only 24 cases of human rabies have occurred since 1924 and since 1970 six of the seven cases have been attributed to bats. In the U.S. 40 cases have been reported since 1990. Of those, 37 were caused by bats.

If a person is exposed to rabies, post exposure prophylaxis (PEP) is given. It consists of rabies immune globulin and a 5 dose series of rabies vaccine. An exposure is a bite, scratch or exposure of non-intact skin or mucous surface to saliva, tears or brain tissue. If the PEP is not given before the onset of neurologic symptoms, it will not work. After exposure, the usual incubation period for rabies is 20-60 days.

There is only ONE unvaccinated rabid patient that has survived. She was a 14 year old girl in Milwaukee who was diagnosed in 2004. She was placed in a chemical coma to slow down metabolism in the brain and given massive anti-viral medications and high dose Vitamin C. She was tested daily for levels of virus neutralizing antibodies in serum and over weeks she survived. The same protocol has been tried on other rabies victims without success.

So the take home message is that any contact with bats carries a risk of rabies. If you are bitten, immediately wash the wound with soap and water and capture the animal if it can be done safely. Local animal control services can assist and test the bat. The Emergency Department will evaluate regarding the need for PEP. Rabies is fatal but preventable with early preventive treatment.

Additionally, clinicians need to recognize that a majority of patients with rabies transmitted by bats might have no recollection of a bat bite so any patient with an unexplained acute, rapidly progressive viral encephalitis needs to have rabies in the differential diagnosis.

BTW…I re watched “Old Yeller” and it doesn’t stand the test of time. It wasn’t nearly as sad or shocking or interesting 40 (or more) years later.

Einstein’s Monoclonal Antibody Shows Encouraging Results In Clinical Trial Of Novel Melanoma Treatment

Sunday, June 29th, 2008

Albert Einstein College of Medicine logoImage via WikipediaPain Therapeutics, Inc. recently announced the successful completion of its first clinical study utilizing a novel melanoma treatment, which the company licensed from Albert Einstein College of Medicine of Yeshiva University. The treatment consisted of dosing patients with a monoclonal antibody labeled with a radioisotope.

A research team at Einstein, led by Arturo Casadevall, M.D., Ph.D., professor and chairman of microbiology & immunology, and Ekaterina Dadachova, Ph.D., associate professor of nuclear medicine and of microbiology & immunology, developed the novel approach to treat metastatic melanoma based on targeting melanin, a skin pigment that is released from dead melanotic tumor cells, with radiolabeled monoclonal antibodies. While the antibodies seek out the released melanin and destroy human melanoma cells with a lethal dose of ionizing radiation, melanin in normal, healthy tissue is not targeted because it is inside the cells and not accessible to the radio-labeled antibody. Small animal studies have demonstrated the feasibility of this approach.

In the recent clinical study, a team of researchers in Israel administered the radiolabeled monoclonal antibody to 12 patients diagnosed with advanced melanoma. Top-line results of this Phase I study indicate this antibody binds to melanoma tumor sites, as evidenced by powerful imaging data obtained by planar scintigraphy and SPECT/CT (single photon emission computed tomography combined with computed tomography). No serious drug-related, adverse events were observed in this study.

“Our initial findings demonstrated how basic research in one area of medicine can yield unexpected benefits for an entirely different field,” said Dr. Casadevall. “We didn’t set out to find a cure for melanoma. Instead, the advance emerged from my study of Cryptococcus, a fungus that can cause fatal infections in people with weakened immune systems and evolved from there. It is exciting when findings take such a promising turn and we are thrilled that this first clinical study using our monoclonal antibody has met with the success that it has thus far.”

“Going from the laboratory to clinical application is what we researchers strive to do so that physicians and their patients can be offered more and better options for treatment,” said Dr. Dadachova. “It is among the most rewarding aspects of conducting research and we are grateful to Pain Therapeutics and our colleagues at Hadassah Medical Center for their efforts to determine how useful this treatment can possibly be. We have great hopes for further success.”

The objectives of the first Phase I study were to assess safety, pharmacokinetics and dosimetry to normal organs. As a result of encouraging data in all of these areas, Pain Therapeutics plans to initiate a second study in which patients will receive increasing amounts of radioactivity delivered by the radiolabeled antibody. The radioactive doses delivered to these patients will be significantly higher than those delivered to the patients of the first study.

At the Society for Nuclear Medicine Annual Meeting in New Orleans, last week, research teams from each of the collaborating laboratories - at Albert Einstein College of Medicine (New York) and Hadassah Medical Center (Jerusalem) presented data related to Pain Therapeutics’ melanoma program. This meeting is considered to be the world’s most significant technical meeting focused on breakthrough developments in clinical imaging and nuclear medicine.

At the meeting, Dr. Dadachova also was presented with an award by the Society’s Young Professionals’ Committee. The award is given in recognition of significant contributions to the fields of nuclear medicine and molecular imaging by young researchers.

Quit Rewarding Drug Impaired

Saturday, June 28th, 2008


I read this morning that a celebratory concert is bring prepared for Nelson Mandela’s 90th birthday in London. He has had a glorious and influential career and is a master statesman known all over the world. How wonderful that he is being honored!

With so many talented performers to choose from, why is Amy Winehouse selected to sing at that concert? Her drug addiction and arrests are also known all over the world. Her husband is awaiting sentencing for attacking a pub owner and it is always a media event to guess if she can perform without falling off the stage.

I know addiction is a disease that progresses without treatment. I am sorry for the waste of talent and the problems Ms. Winehouse faces. She is now reported to have emphysema that will affect her ability to sing.

I’m just tired of seeing impaired “girls gone wild” held up as a shining example of success and to have her on the same stage with a hero like Mandela is just plain wrong.

Surgical Checklist for Patient Safety

Friday, June 27th, 2008

When a pilot sits in the cockpit, she methodically goes through a checklist of all systems and equipment before the plane is fired up. Even if the pilot has flown that plane and route 1000 times, the items on the checklist are reviewed one by one and no-one would think of flying the plane without completing the checklist.

Now, the World Health Organization (WHO) has developed a checklist to be used in the surgical suite by every surgical team before the patient is put to sleep. Up to 16% of surgical procedures result in an unexpected complication. The death rate from surgery in developing nations is an astonishing 10%. A study in Lancet found basic safety measures were overlooked in hospitals around the world.

One of my favorite medical writers is Atul Gawande, a surgeon and Harvard University professor. He worked with WHO and more than 200 worldwide medical organizations to create the checklist.

“What we identified, was that the idea of a checklist to make sure the basic steps are taken, could make a big difference not only in the poorest part of the world but even in the rich ones.”
“We borrowed an idea that pilots have for 75 years,” Gawande said. “It’s like an airline check, you make it short, simple and the team can do better.”

Its primary aim is to target the three biggest cause of mortality in surgery - preventable infections, preventable complication from bleeding, and safety in anesthesia.
It includes six basic steps in care, including verifying that it is the correct patient, ensuring equipment is not left inside the patient, and administering an antibiotic before making an incision - which cuts the risk of infection by half.

A study published in the Lancet, found that before the checklist was used there was a 64% chance that at least one of the procedures was forgotten - with no difference between rich and developing countries. However after implementing the checklist system, failure rates for the first 1,000 patients dropped by half to 32 percent. In a couple of place they cut it to 100 percent. More definitive results will be known later in the year after 3,500 major surgical interventions have been studied.
In the meantime three countries — Britain, Ireland and Jordan — have already adopted the checklist procedures in the operating rooms of their hospitals. I hope the USA follows soon.

WHO officials hope the checklist will be adopted around the world.

California HMOs - Raking in the Dough

Thursday, June 26th, 2008


Health costs and insurance premiums are rising at a rate that is completely unaffordable to companies, the government and to patients who buy their own insurance. We’ve seen these escalating costs for years and everyone who is connected to health care, either as a provider or a buyer knows we are standing at the edge of a cliff with a steep drop off.

So how is it that in 2007, HMOs in California spent $6 billion on administrative costs, which included large CEO salaries? (and that is in addition to billions of dollars in profits) . Talk about waste. That is 6 billion dollars in high premiums. Six billion dollars that did not go toward vaccinations, or mammograms or surgery or nursing care.

UnitedHealth Group, the largest health insurer in the nation, paid it’s CEO $124.8 million in 2004. After an outcry, his salary went down to a paltry $12 million in 2006. Anthem Blue Cross (previously Wellpoint) paid its CEO total compensation of $52.4 million in 2006. That’s enough to provide about 29,000 California children with health insurance. He also gets the use of the company jet and travel for his wife.

HMO plans are only part of the story. For enrollees who buy coverage in Blue Cross PPO plans, only 51 cents of every premium dollar is spent on health care. Profits account for 27% and that is on top of “administration”, which I presume is those juicy salaries and perks.

These HMOs are for-profit, meaning they answer to wall street shareholders who want a return on the dollar. Is that where we want health premiums to go?

The next time a test or doctors visit is denied or you realize your out of pocket deductible is the only amount that is being paid, think about these salaries. Don’t think health care reform is going to come easily. With these amounts of dollars, the incentive for change is a long way off.

Natural Medicine

Thursday, June 26th, 2008
Very often we use complementary natural medicine such as different kinds of herbs, even preferring alternative medicine to modern medicine and sometimes we have all reasons to do that. An herb is plant and we use the plant or part of it for its scent, flavor and therapeutic properties of course. According to the World Health Organization (WHO), as many as 4 billion people, or 80 percent of the earth’s population, are estimated to use a form of herbal medicine in their health care. No doubt herbal medicine is a large part of naturopathic, homeopathic, Native American Indian, Ayurvedic, and traditional oriental medicine.

People which want to improve their health use herbal medicine as a dietary supplements, because herbs have been used for a long time for claimed health benefits. They are sold as tablets, capsules, powders, teas, extracts and fresh or dried plants.

Just don’t forget befour you start to use it

Consult your doctor first
Dont take a bigger dose than the label recommends
Take it under the guidance of a trained medical professional
Be especially cautious if you are pregnant or nursing

FDA Approves GlaxoSmithKline’s New Combination Vaccine For Children

Thursday, June 26th, 2008

A child receives oral polio vaccine during a 2002 campaign to immunize children in India.Image via WikipediaThe US Food and Drug Administration (FDA) announced yesterday that it had given approval for the first new combination vaccine for protecting 4 to 6 year old children against diphtheria, tetanus, pertussis and polio diseases in one shot, made by GlaxoSmithKline (GSK).

The vaccine is branded as the trademarked name KINRIX, and its official long name is Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed and Inactivated Poliovirus Vaccine.

It is approved for use with children who have already received GSK’s Infanrix or Pediarix combination vaccines. Infanrix covers DPT, diphtheria, tetanus and pertussis (whooping cough), and Pediarix covers DPT, hepatitis B and polio.

Health experts tend to recommend combination vaccines because they reduce the number of shots children receive in a single visit.

On Monday, Sanofi Pasteur, part of French drugmaker Sanofi-Aventis SA, announced that the FDA had granted a license for its new 5-in-1 vaccine for use with children under 5 to protect them against diptheria, tetanus, pertussis, polio and Hib disease.

Assistant Clinical Professor of Pediatrics, University of California, San Diego School of Medicine, Dr William P. Hitchcock said in a press statement that:

“Children 4 to 6 years-old can receive five or more vaccinations in a single visit, which can be stressful for parents and vaccinators.”

Reducing the number of vaccine shots a child receives in a visit, combination vaccines like KINRIX may help families meet CDC recommendations and school vaccination requirements, he added.

According to GSK, clinical trial results on KINRIX showed that it offers similar protection to the separate vaccines for Diphtheria and Tetanus Toxoids and Acellular Pertussis (DTaP) and Inactivated Poliovirus (IPV), and it has a similar safety profile.

The Phase III trial of KINRIX was the final confirmation. This comprised a randomized controlled study involving 3,156 US children aged from 4 to 6 years who were vaccinated with KINRIX at the same time as receiving their second dose of measles, mumps and rubella (MMR) vaccine (US licensed M-M-RII).

All the children had already received four doses of DTaP (INFANRIX) and three doses of IPV (IPOL).

Director for US Clinical Research and Development/Medical Affairs at GlaxoSmithKline, Dr Wayde M Weston, said that KINRIX contains the same DTaP and IPV ingredients as INFANRIX and PEDIARIX, two vaccines that doctors in the US have used for many years.

“With the introduction of KINRIX,” said Weston, “eligible 4 to 6 year-olds can receive protection against four serious diseases with one less shot.”

Fake Cancer Cures

Wednesday, June 25th, 2008


It is sad when a patient is dealing with a diagnosis of cancer and believes there is a cure out there that the doctors don’t know about or are keeping from them.

The internet provides more opportunities for a cruel form of greed where fake cancer cures can be dressed up as “scientific” and sold to desperate patients. Bogus cancer cures have been around for decades, but online searches can bring them right to the patient.

The FDA has published a list of “125 Fake Cancer Cures Consumers Should Avoid”. Check it out here.

Firms that engage in cancer treatment fraud often use exaggerated claims that should be red flags to patients and families. Some of them are:

  • “Treats all forms of cancer”
  • “Skin cancers disappear”
  • “Shrinks malignant tumors”
  • “Non-toxic”
  • “Doesn’t make you sick”
  • “Avoid painful surgery, radiotherapy, chemotherapy, or other conventional treatments”
  • “Treat Non Melanoma Skin Cancers easily and safely”

There is a big difference between investigational drugs that are being tested for efficacy and fraudulent products that have never been clinically tested or reviewed.

Painful Truth - Tim Russert

Tuesday, June 24th, 2008


The medical blogosphere writers have been prolific in their speculation about Tim Russert’s untimely death from a myocardial infarction last week. Did he have the right tests? Could more have been done to evaluate and prevent? How could a wealthy, intelligent guy who was under doctor care die from a disease we know so much about?

The best overall summary can be found today in The New York Times. Check it out.
