Allergies Worsening Due to Climate Change

The American Academy of Allergy, Asthma and Immunology and the World Asthma Organization just concluded their joint congress in Orlando, Florida. One of the topics of concern is how climate change is making everyone’s allergy symptoms much worse.

We read about more powerful hurricanes and cyclones, seasonal tornadoes occurring out of season, horrible beach erosion and flooding due to large volume rains, lack of rain causing poor harvests leading to waves of migration for survival for animals and humans. Climate change also exacerbates allergy symptoms. Nelson A. Rosario, MD, PhD, professor of pediatrics at Federal University of Parana (Brazil) discussed longer pollen season and increased allergens caused by fallen trees and ripped up plants, mold growing following flooding and irritants in the air due to wildfires. An international survey in 2015 found that 80% of rhinitis patients blamed their symptom exacerbations on climate change items. Pollen seasons have more than doubled in some areas.

The argument should not be about whether climate change is due to cyclical planetary changes or man-made pollutants. It should be about what we can do as a society to maintain economic growth while limiting man made contribution to adverse climate changes. The health and survival consequences of not addressing this issue will ultimately involve our survival as a species.

Metal Joint Replacement – Should Allergy Testing Be Done First?

As our physically active baby boomers age, more and more of them are facing the need for joint replacement. We run, golf, bike and attend exercise class all in the name of fitness and cardiovascular health.  As a result, many of us have bodies that are becoming beat up and worn.

There have been numerous articles discussing the large increase in knee and hip replacements in active 50 year olds who wish to continue to be as active as they were prior to joint replacement surgery.  An article appeared in this week’s MedPage online journal about a small Italian study conducted regarding chronic pain in “successful “metal joint replacements in the lower extremity. Most of us know someone who had a perfectly unremarkable uncomplicated knee or hip replacement who is now suffering from unexplained pain at the surgically repaired joint site.  X Rays show perfect alignment. CT Scans and MRI scans show perfect surgical alignment. The patient remains in pain.

The study released by Italian researchers’ discusses allergic contact allergy being the cause of the continued pain. The individuals evaluated are allergic to the metals in the artificial joint. In the study subjects were patch tested in advance of joint replacement. Those showing allergic sensitivity to metals contained in the prosthesis received a hypoallergenic product instead. They did not develop the unexplained pain and discomfort and had a great outcome. While the study was small and the results preliminary, it raises the question of whether allergy patch testing prior to elective joint replacement should, and will, become the norm in the future.
