Whooping cough–back again
Jun/27/10 23:24 Filed in: Vaccines | Pseudoscience
Last week, the California Department of Public Health made this announcement:
WHOOPING COUGH EPIDEMIC MAY BE WORST IN 50 YEARS
Date: 6/23/2010
Number: 10-041
Contact: Al Lundeen (916) 440-7259

Urging Californians to get vaccinated now, Dr. Mark Horton, director of the California Department of Public Health (CDPH), warned today that the state is on pace to suffer the most illnesses and deaths due to pertussis, also known as whooping cough, in 50 years.
“Whooping cough is now an epidemic in California,” Horton said. “Children should be vaccinated against the disease and parents, family members and caregivers of infants need a booster shot.”
As of June 15, California had recorded 910 cases of pertussis, a four-fold increase from the same period last year when 219 cases were recorded. Five infants — all under three months of age — have died from the disease this year. In addition, 600 more possible cases of pertussis are being investigated by local health departments.
Pertussis is cyclical. Cases tend to peak every two to five years. In 2005, California recorded 3,182 cases and eight deaths.
Pertussis is a highly contagious disease. Unimmunized or incompletely immunized young infants are particularly vulnerable. Since 1998, more than 80 percent of the infants in California who have died from pertussis have been Hispanic.
The pertussis vaccine is safe for children and adults. Pertussis vaccination begins at two months of age, but young infants are not adequately protected until the initial series of three shots is complete at 6 months of age. The series of shots that most children receive wears off by the time they finish middle school. Neither vaccination nor illness from pertussis provides lifetime immunity.
Pregnant women may be vaccinated against pertussis before pregnancy, during pregnancy or after giving birth. Fathers may be vaccinated at any time, but preferably before the birth of their baby. CDPH encourages birthing hospitals to implement policies to vaccinate new mothers and fathers before sending newborns home. CDPH is providing vaccine free of charge to hospitals.
Others who may have contact with infants, including family members, healthcare workers, and childcare workers, should also be vaccinated. Individuals should contact their regular health care provider or local health department to inquire about pertussis vaccination.
A typical case of pertussis in children and adults starts with a cough and runny nose for one-to-two weeks, followed by weeks to months of rapid coughing fits that sometimes end with a whooping sound. Fever is rare. Read More...

Safety needles
May/04/10 15:02 Filed in: Vaccines | Medical devices
I was speaking to someone recently about safety engineered needle technology, and how much has it entered the medical device market. Safety needles are medical devices that retract or protect the needle after use, so that needlestick injuries can be prevented. The consequences of these type injuries are multifold: spread of blood-borne pathogens such as hepatitis, HIV and other viruses and bacteria, lost productivity of the healthcare worker after injury, and economic and psychological costs of prophylactic treatments or, in a worst case scenario, chronic treatments.
In response to both healthcare workers, industry and politicians, several US Federal and State Agencies began to push for adoption of safety needle products by hospitals and other healthcare settings, mostly from late 1990’s through the early 2000’s. For example, NIOSH (the National Institute of Occupational Safety and Health) announced several recommendations for healthcare workers. OSHA (the Occupational Safety and Health Administration) established regulations for healthcare environments regarding needlestick injuries. Congress passed and the President signed into law the Needlestick Safety and Prevention Act that required regulations to prevent needlestick injuries. Read More...

Case closed
I’ve been off-line for awhile, attending to some other issues in life. However, it’s time for a celebration about the anti-vaccination crowd, including Jenny McCarthy. The US Vaccine Court has ruled that there is no scientific evidence linking vaccinations to autism. To quote ruling:
Petitioners' theory of vaccine-related causation is scientifically unsupportable. In the absence of a sound medical theory causally connecting William's received vaccines to his autistic condition, the undersigned cannot find the proposed sequence of cause and effect to be logical or temporally appropriate. Having failed to satisfy their burden of proof under the articulated legal standard, petitioners cannot prevail on their claim of vaccine-related causation. Read More...

Welfare for health insurance companies
Dec/16/09 22:09 Filed in: Healthcare Policy | Politics
Up until last night, I supported the healthcare reform plans of President Obama. I did so, despite the evisceration of important parts of the proposed law, including the public option, stricter controls on insurance companies, and broader coverage for more people. What we are going to have is a law that is no more than a transfer of wealth from the taxpayers to rich health insurance companies. Sure, those companies have to accept customers with pre-existing conditions, but they get to charge more. Sure, they have to accept older individuals, but they get to charge them more.
Moreover, this bill will charge people who do not have insurance so that they might be covered. If they don’t have the money, the government will give it to you, and it will go to the insurance companies. Senators Joe Lieberman and Mary Landrieu, bought and paid for by the health insurance industry have sold out their values for these companies. Neither of them, supposed Democrats, have shown any conviction, any morals or any beliefs that are not bought in cash. The health insurance companies must be popping corks from bottles of Dom Perignon.
Some people say that it’s better to have a plan than none. I disagree. I think this plan will bankrupt the country, but in a wholly different way that the Republicans are saying. Without real reform, the cost to the citizens will be tremendous. Read More...

Book review–Don't Swallow Your Gum!: Myths, Half-Truths, and Outright Lies About Your Body and Health
I just finished reading Don't Swallow Your Gum!: Myths, Half-Truths, and Outright Lies About Your Body and Health (ISBN:031253387X, 2009) written by Aaron Carroll MD and Rachel Vreeman MD, both pediatricians and researchers at the University of Indiana School of Medicine.
First of all, the book is an amusing, easy read, using terms like “snot” and “poo” to describe bodily secretions. At some 200 pages, it was a quick read, not requiring a lot of time. Obviously, the book was written for a wide audience, debunking many pseudoscientific myths about health. For those of us who demand supporting research, it has a vast list of primary and secondary research citations for further reading. In fact, for me, those citations are going to be invaluable in future articles.
The book goes about debunking silly myths such as “don’t swallow your gum because it will get stuck in your intestine for 5 (10, 20, whatever) years” or the old “five second rule” which we all suspected wasn’t wise. There was one chapter on “double dipping”, which was popularized on a Seinfeld episode many years ago, in which the authors discussed research that showed that double dipping does in fact transfer a lot of germs from the chip to the dip. Not that I would confess to being a double dipper, but I may not be a single-dipper at a party after reading this book! Read More...

Science, lies, and stolen emails
As this is a blog about medicine, I haven’t written much about global warming. Moreover, until a few months ago, I was a bit of a skeptic about the science behind global warming. My skepticism was centered on a few key points that I didn’t feel had been adequately addressed:
Of course, my feelings on global warming would demolish my bona fides to be skeptical about alternative medicine and other pseudoscience. However, I thought the true global warming deniers (and even more so, those who deny the human cause of global warming) were true pseudoscientists, so I decided to study it myself, learning as much as I could about the subject. As I did, my skepticism faded. I found out that the Medieval Warm Period wasn’t as warm as I presumed, and that there is little global evidence that it was actually warmer then compared to today. In fact, regional differences in temperature can be large. I guess it goes back to correlation vs. causation. I was being pseudoscientific in my early thinking about global warming.
Actually, my discomfort with the much of what I was hearing from global warming deniers was similar to what I read from the anti-vaccination crowd. Each of the climate change denier’s pseudoscience is easily debunked. Read More...
- First, I was unconvinced that current temperatures exceeded that of the Medieval Warm Period, a period of warm climate in the North Atlantic from about 800 to 1300. During this time, the weather was warm enough for the Vikings to colonize Greenland and to support a settlement in Newfoundland.
- Second, California glaciers (yes California has numerous glaciers), like Palisade Glaciers in the Sierra Nevada mountain ranges were only about 700 years old, so obviously (to me), it’s colder today than it was before these glaciers formed.
- Third, the earth is just so complicated, it might take hundreds if not thousands of years of data to see any real trends.
