Why Biologicals Make Sense for Treating Asthma
Asthma is a disease of the lung airways. It is different from all other diseases of the lungs in that no other contributory factors are involved. So theoretically, once the restriction of the airways is resolved, the lungs retain normal structure and performance. Aside from the tightening of the muscle layers of the airway, which causes contraction, there is also an inflammatory reaction that causes a thickening of the inner layer of the airways. The net result is a narrowing of the inner space of the airways. This makes it much harder to move air deep into the lungs. That is the essence of the shortness of breath that accompanies asthma. The treatment strategy for asthma is to prevent this inflammation before it happen, or resolve the inflammation when it does occur. To do that, one must understand the complicated process that involves many cells, chemicals, and protein antibodies at many different levels, causing the inflammation. Years ago when lecturing medical students using

What is Severe Asthma?
Researchers have learned that 5-10 percent of asthmatics do not respond well to traditional asthma medications, making their asthma difficult to control. In order to better help these asthmatics, researchers now categorize them under a special asthma subtype called Severe Asthma. So, what is severe asthma, and what does it mean if you have it? What is it? Sally Wenzel, professor of medicine at the University of Pittsburgh, defines severe asthma as “patients who require high dose inhaled glucocorticoid (GC), or continuous or near continuous oral GC treatment to maintain asthma control or who never achieve control despite that treatment.” It was defined as an asthma subtype less than 15 years ago. What is it not? Severe asthma must not be confused with other causes of difficult to treat asthma, including: Asthma exacerbated by uncontrolled asthma triggers (You have allergic asthma and have attacks when exposed to molds)
Asthma and Anaphylaxis: What you need to know
Anaphylaxis is a severe and life threatening allergic reaction that occurs within seconds-to-minutes of contact with the allergen - such as a food or bee venom. If you or your child has asthma the risk of having this type of reaction is compounded. While you can't prevent or predict every allergic reaction there are things you can do to decrease the likelihood of a fatal reaction.Talk to your doctor.If you or your asthmatic child has any history of allergic reaction you need to talk with your physician about whether you should be carrying an Epi-pen. My personal opinion is - when in doubt carry an Epi-pen. The severity of previous reactions does not predict how severe the next reaction will be. You definitely don't want to find this out the hard way.Know the symptoms and treatment for anaphylaxis.Anaphylaxis can present symptoms like hives, itching, flushed or pale skin, lump in the throat, problems breathing, dizziness, fainting, nausea and vomiting. Symptoms of anaphylaxis can go from bad to worse quickly so treatment has to be administered quickly. In an emergency situation the
Second hand Smoke is a Danger to Kids
Imagine a child who never smoked cigarettes, growing up and developing chronic obstructive pulmonary disease or COPD, simply because they live in a home where smoking occurs. This is a true medical tragedy. It is also avoidable. In an earlier sharepost, I discussed the Hygiene Hypothesis which explains how certain factors in an infant’s early upbringing can predict the likelihood of developing asthma later in life. Specifically, I discussed the benefit of exposure to certain childhood infections, and how that can influence optimal immune cell development and protect the child from developing asthma later-in-life. There is new evidence supporting what experts like me have suspected. Children who are exposed to second hand smoke in their homes have a double risk for hospitalization for asthma. According to a recent research review at the Mayo Clinic Children Research Center, kids alr
