Here are some of the latest health and medical news
developments, compiled by the editors of HealthDay:
Female Sexual Enhancement Supplement Recalled
A female sexual enhancement supplement called RegenArouse is
being recalled after a U.S. Food and Drug Administration analysis
of the product confirmed the presence of tadalafil, a drug (brand
name Cialis) used to treat male erectile dysfunction.
The presence of tadalafil makes RegenArouse an unapproved drug
that may pose a threat to consumers because it may interact with
nitrates found in some prescription drugs and may lower blood
pressure to dangerous levels, the FDA said.
People with diabetes, high blood pressure, high cholesterol or
heart disease often take nitrates.
The nationwide recall is for RegenArouse, lot number 130100, a
pink capsule sold individually in foil packets, expiration date
12/5/2013, UPC code 816860010079. The product was sold over the
Internet to consumers in the U.S. and Puerto Rico between Nov. 29,
2011 and Feb. 10, 2012.
Consumers with the recalled product should return any unused
product to Regeneca Inc. for an exchange or full refund, the FDA
Cancer Drug Shortage Threatens Children's Lives
A shortage of the childhood leukemia drug methotrexate in the
United States means that hospitals across the country may run out
of the medicine within the next two weeks.
If that happens, cancer doctors and federal officials say that
hundreds and perhaps thousands of children will be at risk of dying
from a largely curable disease,
The New York Times reported.
Methotrexate is used to treat acute lymphoblastic leukemia
(ALL), which is most common in children ages 2-5. One of nation's
largest suppliers of injectable preservative-free methotrexate was
Ben Venue Laboratories. But in November, the company suspended
operations at its plant in Bedford, Ohio due to what it called
"significant manufacturing and quality concerns."
"This is a crisis that I hope the FDA's hard work can help to avert," Dr. Michael P. Link, president of the American Society of Clinical Oncology, told The Times. "We have worked very hard to take what was an incurable disease and make it curable for 90 percent of the cases. But if we can't get this drug anymore, that sets us back decades."
Rare Brain Disease Strikes Two People in California
Two cases of a rare and fatal brain disease are being
investigated by the Marin County Department of Public Health in
One woman is dead and another sick after developing
Creutzfeldt-Jakob disease. The two cases are thought to be
ABC News reported.
"We have no evidence that suggests a causal linkage between the suspect cases nor is there any evidence to suggest a risk in [the] food supply," the health department said in a statement.
Creutzfeldt-Jakob disease occurs in about one in a million
people each year, according to the U.S. Centers for Disease Control
and Prevention. The cause in most cases is unknown, but a small
number of cases are inherited,
ABC News reported.
Some cases -- called variant Creutzfeldt-Jakob disease -- are
linked to mad cow disease. That's been ruled out in one of the
Marin County cases and officials suspect the second case is also
unrelated to mad cow disease.
Immune Cells Use Unique Method to Fight HIV: Study
Some types of immune cells resist HIV by denying the
AIDS-causing virus the building blocks of life, according to a new
Because viruses cannot replicate on their own, they have to take
over other cells and use them to produce new viruses,

The international team of researchers found that some immune
system cells destroy their own raw materials in order to stop HIV.

be harnessed for HIV therapy,
