Two cases of people in Louisiana who died after contracting "brain-eating amoeba" infections from their own household water systems are prompting health officials to warn about a popular home remedy for treating sinus problems and allergies.

People who use neti pots to irrigate their nasal passages and sinuses should use only water that has been boiled, filtered or distilled, said the researchers at the Centers for Disease Control and Prevention who investigated the unrelated cases, which occurred months apart in 2011 in different parts of Louisiana.

The cases are the first evidence reported in the U.S. of municipal, disinfected tap water used in nasal irrigation causing infections of Naegleria fowleri, as the amoebas are properly called. The infections which pass into the brain from the nose are almost always deadly, with only one report of a survivor ever documented in the U.S., according to the CDC.

Infections have only been known to occur in cases in where water is forced up the nose, Yoder said. There have not been any cases where people contracted the infections by bathing or showering, and "there is certainly not a risk with drinking water," he said.

Pass it on: Neti pot users should use only sterile water, which has been boiled, distilled or filtered, the CDC says.

I'm not sure if this thread is the best place for this, but I couldn't think of where else would be.

I just found out that the "shingles" vaccine age limit has been lowered from 60 to 50. If you don't know what it is, check into it (zoster virus). If you have ever had chickenpox you carry the virus in your system. It usually only affects people who are over 60 years of age or have some compromise in their immune system.

Even if you do not fit into this group you can get it. I have had it twice, both times in my forties, five years apart and had no other health issues. You don't want to get it. Check with your health care provider to see if it would be a good idea for you.

This change was made in March 2011, I have been told by two different pharmacies since then that the age was still 60. This is incorrect, you can now get it a participating Costco pharmacies (and probably others). Check your insurance, because this one isn't cheap without it. $188.00 Ouch.

Not giving medical advice, just encouraging folks to check into it this vaccine season and learn about it.

I think this is the best place for this tidbit of happy information.

I get my health care at the San Francisco Veterans Administration Medical Center. Today at the VA it was Transgender Awareness Day and there was a half day mini conference (with CME/CEU) on Transgender Health with 3 presentations.It was a great conference and I talked about all of it in the Trans News thread, but I wanted to post this part here for a wider audience....

Marci Bowers, MD is probably the best known surgeon who does Sex Reassignment Surgery was one of the presenters. The best and most interesting thing I heard from her had to do with female genital mutilation/female circumcision. It seems the damage can be repaired and a woman will end up with normal looking and functioning genitalia. Yes it can be fixed with what she called 'a simple surgery'.The clitoris works and they can have vaginal penetration and even deliver a baby. She is the only surgeon (she knows about) in the US that is doing this surgery and she does every one of them pro bono. There are surgeons who Europe who do it and she went to Paris and trained. I was stunned and so were the rest of the audience.

Op Ed piece in NYTimes today, May 14, 2013:

Angelina Jolie's doctors estimated that She had an 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer, although the risk is different in the case of each woman.

She recently underwent a double mastectomy to try to proactively beat the odds due to having an inherited gene mutation. Those with a defect in BRCA1 have a 65 percent risk of getting breast CA, on average. Her mom died of breast CA at age 56.

Dementia rates drop sharply, as predicted

By Gina Kolata

A new study has found that dementia rates among people 65 and older in England and Wales have plummeted by 25 percent over the past two decades, to 6.2 percent from 8.3 percent, a trend that researchers say is probably occurring across developed countries and that could have major social and economic implications for families and societies.

Another recent study, conducted in Denmark, found that people in their 90s who were given a standard test of mental ability in 2010 scored substantially better than people who had reached their 90s a decade earlier. Nearly one-quarter of those assessed in 2010 scored at the highest level, a rate twice that of those tested in 1998. The percentage of subjects severely impaired fell to 17 percent from 22 percent.

The British study, published on Tuesday in The Lancet, and the Danish one, which was released last week, also in The Lancet, soften alarms sounded by advocacy groups and some public health officials who have forecast a rapid rise in the number of people with dementia, as well as in the costs of caring for them. The projections assumed the odds of getting dementia would be unchanged.

Yet experts on aging said the studies also confirmed something they had suspected but had had difficulty proving: that dementia rates would fall and mental acuity improve as the population grew healthier and better educated. The incidence of dementia is lower among those better educated, as well as among those who control their blood pressure and cholesterol, possibly because some dementia is caused by ministrokes and other vascular damage. So as populations controlled cardiovascular risk factors better and had more years of schooling, it made sense that the risk of dementia might decrease. A half-dozen previous studies had hinted that the rate was falling, but they had flaws that led some to doubt the conclusions.

Researchers said the two new studies were the strongest, most credible evidence yet that their hunch had been right. Dallas Anderson, an expert on the epidemiology of dementia at the National Institute on Aging, the principal financer of dementia research in the United States, said the new studies were “rigorous and are strong evidence.” He added that he expected that the same trends were occurring in the United States but that studies were necessary to confirm them.

“It’s terrific news,” said Dr. P. Murali Doraiswamy, an Alzheimer’s researcher at Duke University, who was not involved in the new studies. It means, he said, that the common assumption that every successive generation will have the same risk for dementia does not hold true.

The new studies offer hope amid a cascade of bad news about Alzheimer’s disease and dementia. Major clinical trials of drugs to treat Alzheimer’s have failed. And a recent analysis by the RAND Corporation — based on an assumption that dementia rates would remain steady — concluded that the number of people with dementia would double in the next 30 years as the baby boom generation aged, as would the costs of caring for them. But its lead author, Michael D. Hurd, a principal senior researcher at RAND, said in an interview that his projections of future cases and costs could be off if the falling dementia rates found in Britain held true in the United States.

Dr. Marcel Olde Rikkert of Radboud University Nijmegen Medical Center in the Netherlands, who wrote an editorial to accompany the Danish study, said estimates of the risk of dementia in older people “urgently need a reset.”

But Maria Carrillo, vice president of medical and scientific relations at the Alzheimer’s Association, an advocacy group, was not convinced that the trends were real or that they held for the United States.

The studies assessed dementia, which includes Alzheimer’s disease but also other conditions that can make mental functioning deteriorate. Richard Suzman, the director of the division of behavioral and social research at the National Institute on Aging, said it was not possible to know from the new studies whether Alzheimer’s was becoming more or less prevalent.

The British researchers, led by Dr. Carol Brayne of the Cambridge Institute of Public Health, took advantage of a large study that tested 7,635 randomly selected people, ages 65 and older, for dementia between 1984 and 1994. The subjects lived in Cambridgeshire, Newcastle and Nottingham. Then, between 2008 and 2011, the researchers assessed a similar randomly selected group living in the same areas.

“We had the same population, the same geographic area, the same methods,” Dr. Brayne said. “That was one of the appeals.”

But Dr. Carrillo questioned the data because many subjects had declined to be assessed: the researchers assessed 80 percent of the group it approached in the first round and 56 percent of those approached in the second. Her concern is reasonable, Dr. Brayne said, but the researchers addressed it by analyzing the data to see if the refusals might have skewed the results. They did not.

In the Danish study, Dr. Kaare Christensen of the University of Southern Denmark in Odense and his colleagues compared the physical health and mental functioning of two groups of elderly Danish people. The first consisted of 2,262 people born in 1905 who were assessed at age 93. The second was composed of 1,584 people born in 1915 and assessed at age 95. In addition to examining the subjects for physical strength and robustness, the investigators gave them a standard dementia screening test, the mini-mental exam and a series of cognitive tests.

The investigators asked how many subjects scored high, had scores indicating dementia and were in between. The entire curve was shifted upward among the people born in 1915, they discovered.

Dr. Anderson, of the National Institute on Aging, said the news was good.

“With these two studies, we are beginning to see that more and more of us will have a chance to reach old age cognitively intact, postponing dementia or avoiding it altogether,” he said. “That is a happy prospect.”

An earlier version of this article misspelled the name of the medical center where Dr. Marcel Olde Rikkert works. It is the Radboud University Nijmegen Medical Center in the Netherlands, not Nigmegen.

STUDY: LATER RETIREMENT MAY HELP PREVENT DEMENTIA

BY MARILYNN MARCHIONE
AP CHIEF MEDICAL WRITER

BOSTON (AP) -- New research boosts the "use it or lose it" theory about brainpower and staying mentally sharp. People who delay retirement have less risk of developing Alzheimer's disease or other types of dementia, a study of nearly half a million people in France found.

It's by far the largest study to look at this, and researchers say the conclusion makes sense. Working tends to keep people physically active, socially connected and mentally challenged - all things known to help prevent mental decline.

"For each additional year of work, the risk of getting dementia is reduced by 3.2 percent," said Carole Dufouil, a scientist at INSERM, the French government's health research agency.

I don't know that the researchers proved working in ones later years influences dementia related diseases. I'm not fond of studies that use records (as opposed to interviewing people) as the source of their data. There are too many unknown and unaccounted for variables.

What they have reproven (ad nauseum) is that "being physically active, socially connected and mentally challenged - all things known to help prevent mental decline."

Baby boomers are proving one doesn't have to work to stay physically active, socially connected, and mentally challenged.
