Tylenol Dose Lowered

McNeil Consumer Healthcare Division of McNEIL-PPC, Inc. ("McNeil") announced plans for new dosing instructions lowering the maximum daily dose for single-ingredient Extra Strength TYLENOL® (acetaminophen) products sold in the U.S. from 8 pills per day (4,000 mg) to 6 pills per day (3,000 mg). The change is designed to help encourage appropriate acetaminophen use and reduce the risk of accidental overdose.

Is it Allergies or is t a Cold?

Although allergies and colds have similar symptoms, there are some signs that can help you tell the difference between them. It is probably an allergy if:

  • Mucous secretions are clear and runny.

  • Sneezes occur in a rapid sequence.

  • Itchiness in nose, ears and throat (especially the palate or roof of the mouth) is present.

  • Symptoms of seasonal allergies usually last longer than the typical duration of a cold, which is usually 7 to 10 days.

H5N1 Flu Virus - What is new on horizon?

A submitted paper that describes a modified strain of the avian H5N1 virus has the scientific community discussing the dangers of publishing science that could be used for bioterrorism.

In the paper submitted to Science, Dutch scientist Ronald Fouchier and his team at Erasmus Medical Centre in Rotterdam, the Netherlands report that by transferring a strain of H5N1 from ferret to ferret, the virus evolves to adapt to each host. The virus’ normal mechanism for transmission is via bodily secretions, but Fouchier and colleagues found that the virus became capable of airborne transmission after only 10 generations in the experiment.

Because ferrets and humans share a similar immunity to the H5N1 virus, some are concerned that the strain could be just as contagious among humans as the common flu. While the common flu is relatively harmless to otherwise healthy people, it still kills thousands each year so a H5N1 strain capable of airborne transmission has the potential to be much more deadly. Wild H5N1 strains currently aren’t easily transmissible among people; most cases occur from contact with infected birds.

Recent warming is associated with increased length of ragweed pollen season

A fundamental aspect of climate change is the potential shifts in flowering phenology and pollen initiation associated with milder winters and warmer seasonal air temperature. Earlier floral anthesis has been suggested, in turn, to have a role in human disease by increasing time of exposure to pollen that causes allergic rhinitis and related asthma. However, earlier floral initiation does not necessarily alter the temporal duration of the pollen season, and, to date, no consistent continental trend in pollen season length has been demonstrated. Here we report that duration of the ragweed (Ambrosia spp.) pollen season has been increasing in recent decades as a function of latitude in North America. Latitudinal effects on increasing season length were associated primarily with a delay in first frost of the fall season and lengthening of the frost free period. Overall, these data indicate a significant increase in the length of the ragweed pollen season by as much as 13-27 d at latitudes above ∼44°N since 1995. This is consistent with recent Intergovernmental Panel on Climate Change projections regarding enhanced warming as a function of latitude. If similar warming trends accompany long-term climate change, greater exposure times to seasonal allergens may occur with subsequent effects on public health. 

Dr. Leonard Bielory was a coathor on this study and is presently funded by the US EPA through Rutgers University to developmodels for future impact of allergies on the US population.
