Cold and Flu
There are a number of conditions that can cause a cough to linger for weeks or months. Doctors treating patients with a chronic cough should consider both the more likely and less common possibilities. When a cough persists after those possibilities have been ruled out or treated, new research suggests that irritated nerve ending in the “cough centers” of the airways could be behind a chronic cough.
The term “pneumonia” encompasses a number of illnesses and infections. Some are more serious than others, and some are more easily treated than others. Since pneumonia has dominated the news cycle for the past few weeks, we’ve put together some definitions to demystify this catchall term for a range of lung conditions.
If you have been avoiding the flu shot because you’re allergic to eggs, studies suggest that you can safely get vaccinated. Allergic reactions to the flu shot are quite rare. If you’ve never had a reaction to a flu shot, protect yourself by getting one this year. Ideally do it in a doctor’s office or hospital so that you can get prompt treatment in the unlikely event you have an immediate, severe reaction.
Many people with sinus infections expect to be given antibiotics for treatment, but in most cases the infection will improve on its own. If a person’s symptoms meet certain criteria — for example, when colorful nasal discharge and facial pressure and pain last for more than 10 days — then antibiotics are recommended.
For years, many kids could skip the traditional flu “shot” — along with the tears — and still be protected by the nasal spray vaccine also known as the LAIV (live attenuated influenza vaccine). But not this year. Studies now show that the nasal vaccine is quite ineffective, and pediatricians are starting to change their flu recommendations from a nose squirt to a shot.
Many people still think the color or consistency of nasal discharge determines whether you have a sinus infection. The truth is that anything that irritates the nose’s delicate lining — whether a virus, bacterium, or allergen — can result in any color or consistency of discharge. In fact, viruses are the most common cause of sinus infections, meaning you shouldn’t run to your doctor based on your mucus color alone.
Many common cold and flu medications and prescription-strength pain relievers contain acetaminophen (Tylenol) as one of their active ingredients. If you take several of these drugs at once during a bout of cold or flu, you might accidentally take more than the safe dose of acetaminophen, potentially causing liver damage. It’s always best to read the labels — and to keep in mind that most winter viruses get better on their own with rest, fluids, and time.
If your baby is sick with fever, cough, and wheezing, it’s natural to think he or she needs medication. But if the culprit is bronchiolitis — a bad cold that has settled into the lungs — the best treatment is usually no treatment at all. That’s because treatments like antibiotics don’t work against bronchiolitis, and can cause unwanted side effects. Of course, you should always check in with your doctor if you think your baby has bronchiolitis.
The statin drugs are very effective at reducing LDL (“bad”) cholesterol and may also reduce inflammation throughout the body. Both of these properties can reduce the risk of cardiovascular problems. At the same time, research — some of it conflicting — suggests that statins may also affect the body’s immune system. In particular, they may dampen the response to vaccines.
“Last time I got the flu shot, it actually made me sick!” “My kids are perfectly healthy. They’ll be fine.” You’ve probably heard a version of these two before. These flu shot myths are so persistent that they prevent countless numbers of people from getting vaccinated each year. We’ve debunked these claims here to help you make your flu shot decision based on facts — not myths.
