Volume 20    Number 1     

December 2020 – February 2021



            We welcome all new and established patients to our newsletter.  This is formulated four times a year to inform patients and the medical community with regard to new developments in asthma, allergies, and clinical immunology.  Please feel free to take this home with you and share it with family and friends. 


Winter Allergens

With winter, patients can often have an increase in their indoor allergy symptoms. This is because we spend more time indoors and we have less air circulation with the outdoors as windows are closed and air is being recirculated in order to heat the indoor air.

Common indoor allergens include molds, animal dander, and dust mite particles. Indoor plants can sometimes be a cause of indoor allergen sensitivity. However, this can be difficult to diagnose as we do not have standardized skin test products for many indoor plants. If you have any questions regarding indoor allergies, please do not hesitate to contact us.


Wintertime Infections

            It is well known that people often have increased pneumonia and sinus problems during the late fall and winter, i.e. November through March. Certain bacteria and viruses have more activity in the wintertime. There are many reasons for this. Included in that is that the indoor air is dry in the wintertime leading to irritated skin of the airways which is then fertile breeding ground for bacteria and viruses to settle in. Indoor allergy symptoms can be more significant during the wintertime. This is also a setup for infection. Certain viruses and bacteria do not do well when exposed to ultraviolet light. With people being indoors more, they are not exposed to the natural anti-infectious benefits of sunshine. It is thought that vitamin D can be playing a role in increasing one’s susceptibility to infection. Therefore, vitamin D supplementation in our part of the country is, I believe, vital to keeping one’s airway healthy. If you have any questions regarding this, please do not hesitate to contact us.


Everything That is Illness is not Covid-19

            It is well known that COVID-19 infection is in almost all cases not life-threatening. Even in those over the age of 75 years of age, for every 100 people over the age of 75 who get COVID-19 more than 94 of them will survive COVID infection.

            A study conducted by the Michigan Department of Health showed that there was a 62% increase in out-of-hospital deaths from the end of March to the end of May 2020. The CDC has shown an over 40% decrease in the diagnosis of six major cancers from January through the end of April 2020 in the United States. There has been a 43% increase in suicides according the Michigan Department of Health.

            These statistics are sobering. The undue fear that has taken over many Americans has led to a multitude of problems. A significant issue is that the main death rate of COVID-19 may not be from the infection itself but actually as a consequence of fear. Isolation of individuals can be deadly. Misinformation can also be a significant risk factor for health problems or death during these times. It is strongly recommended that people educate themselves and find trusted and reasonable sources of information regarding COVID-19.

 Around the Mitchell House

We continue to maintain one of the most historic buildings in Wexford County. The Mitchell house was built by the founder of Cadillac, George Mitchell. This summer, we had tuck pointing completed around this building. This will help to maintain building for many years to come. We are extremely diligent in choosing what we believe to be the best possible craftsman to maintain this excellent building. Many of them are local. We consider ourselves caretakers more than owners of this important structure. A big thanks goes to Gwen Dubravec, founder and director of the Cadillac Preservation Guild, for her efforts in overseeing the restoration and maintenance of this building.
