How Safe is Vaping

Vaping, so called because it consists of inhaling the vapour emitted by a device, usually involves a variety of electronic vapour-producing products including e-cigarettes (EC), e-cigars, e-pipes, e-hookahs, hookah pens, vape pens and vaping pipes.

Effects of Pollution - Part 3

Part 1 of this series titled When Breathing is Bad for You explained how air quality is measured and the effects of air pollution on mortality. Part 2 described its effects on the fetus, the DNA damage incurred and the effects on the cardiovascular and respiratory systems. Part Part 3 continues the list of other effects of air pollution.

While pollutants such as NO2, CO, O3 and SO2 did not have a significant effect, PM 2.5 did. Within hours of exposure to PM 2.5 levels considered safe by the EPA, the risk of ischemic stroke rises. . . .

Effects of Polluted Air - Part 2

Air pollution affects both morbidity and mortality. The level of pollutants varies with location, altitude, temperature and wind patterns. The effect of air pollution is equally variable, the more susceptible an individual, the greater the effects of pollution. Exposure to high density traffic – nearness to roads with high traffic volumes as well as high diesel exhaust levels – also contribute to . . .

Oh, the errors they make (with inhalers)!

Inhalation devices used in asthma to deliver medication are designed to get the medication  directly into the lungs.

Failure to complete these steps results in inadequate dosages being administered, and this in turn can result in acute episodes of asthma.

Who Dies From Asthma?

The answer is: people of all ages. 180,000 people across the world die from asthma each year. The United States records about 70 deaths a week, most of them preventable. In the United Kingdom, 20 persons die each week. The question hence arises: why were these deathsnot prevented?

A study by the British Thoracic Association of 90 asthma deaths found that 74% occurred because patients underestimated the severity of the disease. In 36 instances, the patients saw a health care provider . . .

Polypharmacy in the Elderly – Part 2: The Solution

There is one further complication when dealing with the elderly. It may be that they feel they are wasting a health care provider’s (HCP) time; or they may feel that the situation is not serious enough to warrant a visit to their HCP; or they seek advice from friends to the extent that they are known to not only take medication that has been prescribed for themselves but also . . .

Who Is Speaking Asthma? - Part 1

Medical terminology has held both a degree of fascination and intimidation for patients who are unfamiliar with it. Between health care professionals, the use of terminology is deliberate and easily understood. It aids communication and becomes a shorthand for conveying a volume of information in a few words. However, while it is helpful for health care professionals, one needs to carefully examine and even question . . .
