Nearly all of the herbal dietary supplements tested in a Congressional
investigation contained trace amounts of lead and other contaminants,
and some supplement sellers made illegal claims that their products
can cure cancer and other diseases, investigators found.

The levels of heavy metals — including mercury, cadmium and arsenic —
did not exceed thresholds considered dangerous, the investigators
found. However, 16 of the 40 supplements tested contained pesticide
residues that appeared to exceed legal limits, the investigators
found. In some cases, the government has not set allowable levels of
these pesticides because of a paucity of scientific research.

New Way Bacterium Spreads in Hospital

Health care workers and patients have yet another source of hospital-
acquired infection to worry about, British researchers are reporting.

Clostridium difficile, a germ that causes deadly intestinal infections
in hospital patients, has long been thought to be spread only by
contact with contaminated surfaces. But a new study finds that it can
also travel through the air.

The researchers emphasized that there is no evidence that C. difficile
can be contracted by inhaling the germs. Rather, they float on the
air, landing in places where more people can touch them.

The bug is commonly spread by contact with infected feces, and the
British scientists said the new study made it even more urgent to
isolate hospital patients with diarrhea as soon as possible — even
before tests confirm a C. difficile infection.

“We don’t want people to wait for the confirmation,” said the study’s
senior author, Dr. Mark H. Wilcox, a professor of medical microbiology
at the University of Leeds. “By then, the cat’s out of the bag.”

Outbreaks of C. difficile, a bacterium resistant to many antibiotics,
have been increasing in the United States since 2001, along with the
evolution of more virulent strains.

People in good health are rarely infected. But broad-spectrum
antibiotics can wipe out the bacteria that normally live in the
intestines, allowing C. difficile to flourish. Hospitalized people on
antibiotics and the elderly, even when not taking medicine, are at
high risk.

Health care workers who touch contaminated feces can spread the
disease by direct contact with other people or just by touching
objects. The spores are resistant to disinfectants and can survive in
open areas for months.

The bacterium produces toxins that can cause fever, nausea, abdominal
pain, severe diarrhea — and sometimes colitis, a serious inflammation
of the large intestine.

Treatment involves replacing the broad-spectrum antibiotics with other
antibiotics, usually vancomycin or metronidazole.

The British researchers began with a six-month investigation of 50
patients, symptomatic and not, with confirmed infection. The air near
12 percent of them was found to be contaminated with C. difficile. The
more active their diarrheal symptoms, the more likely they were to
have spores in the air around them.

Then the scientists repeatedly tested 10 patients with symptomatic
illness over a 10-hour period, and the air near 7 was positive for c.
difficile, usually during visiting hours or when there was activity in
patient rooms like food delivery, ward rounds or bedding changes.
Surfaces around 9 of the 10 patients were also contaminated.

The scientists believe that the movement of people and the opening and
closing of doors stir up spores on contaminated surfaces, helping them
disperse and increasing the possibility of them spreading.

The finding is unlikely to change current preventive practice, said
Dr. L. Clifford McDonald, an epidemiologist at the Centers for Disease
Control and Prevention. He said that the study supported putting
patients in a single room, “which is the norm here in the U.S.”

“There is a little bit of dispersion,” he added, “but the heavier
contamination is still from direct contact.”

Dr. Wilcox agreed. “It’s important,” he said, “not to interpret the
results as a justification for methods aimed at removing bacteria from
the air, techniques that may be appropriate for highly
immunocompromised patients, but not for those at risk for C. diff
infection.”

The amounts of C. difficile found in the air were generally modest.
There were no clouds of germs circulating in patients’ rooms. This may
suggest a genuinely low level of airborne contamination, the
researchers write, or it may be a result of methodological problems in
collecting air samples: the initial location of the sampling devices,
their design, or their movement to accommodate patient care or the
arrival of visitors.

Dr. Wilcox said patients should protect themselves from C. difficile
by the conscientious application of two substances that do not require
a prescription: soap and water.

“For everyone in a hospital, staff or patients,” he said, “the chief
thing is optimal hand hygiene.”

Since supplements are touted as alternative, I felt that people should
know what they are ingesting. The fact that an infection, which is
ubiquitous can spread through the air has nothing to do with it.

According to Janet Drew these would kill everyone that tried it.

One drop of mercury kills, she says. LOL
