Ahwatukee Oak Alley

I attended medical school in New Orleans.  Along with great food, music and the rich culture and history, one of my fondest memories was the magnificent Southern Oak trees. These ancient giants, some dating back to the Civil War, with trunks the size of a Volkswagen beetle, hanging with moss, framed an idyllic image of […]

Arizona Olive Trees: Life Will Find a Way

Reproduction is one of the most powerful forces in nature. In the plant world, this power is on grand display every spring in the form of fantastic flowers and although flowers look and smell nice,  it’s all business for the plant. When plants require the services of insects such as bees to deliver pollen from one […]

“Didn’t We Do This Last Year?”

I am reposting an article that I wrote (almost to the day) a year ago.  At that time we were experiencing an unusually early “spring” allergy season starting in late January.  Well, here we go again. The Ash trees began pollinating two to three weeks earlier than usual again this year and, by the looks […]

Arizona Air Quality: Ozone and Outdoor Exercise

I am discussing air quality in Arizona, particularly as it affects patients with allergies and asthma. Previously, one of the most important pollutants, Ozone was discussed and in this post I will continue with some of the special problems associated with ozone exposure and outdoor exercise. For a number of reasons, athletes are particularly vulnerable […]

Air Quality in Arizona: Ozone

I will continue the discussion on air quality in Arizona, particularly as it affects patients with allergies and asthma, beginning with one of our most important pollutants: ozone. Ozone in the upper atmosphere is our friend.   This thin layer of gas floating between 6 and 31 miles above the earth’s surface protects life on our […]

Arizona Air: The Good the Bad and the Ugly

Phoenix is a wonderful place to live if you enjoy spending time out of doors.  However, there is a catch. The conditions that make for our predictable-practically-perfect weather (at least in the winter and spring) has also led to some serious air quality issues. Every year the Arizona Department of Environmental Quality releases a number […]

Exercise Induced Bronchoconstriction: Diagnosis

On the surface, making a diagnosis of exercise-induced bronchoconstriction (EIB) should not to be too hard. After all, having an asthma attack while exercising would make the diagnosis fairly apparent.  However, as I mentioned earlier, self reported symptoms associated with exercise such as shortness of breath and chest tightness can be associated with a number […]

Exercise Induced Bronchoconstriction: What, When, and Where

Exercise-induced bronchoconstriction or bronchospasm (EIB) is defined as acute airway narrowing occurring as a result of exercise.  In the previous post I discussed that exercise, particularly vigorous, aerobic exercise, frequently triggers symptoms in patients who have a diagnosis of asthma but can also cause asthma symptoms, wheezing, shortness of breath, cough, and chest tightness, in […]
