Pets in home: many allergy studies, mixed results

By Sasha Klemawesch, MD Finally, scientific proof of dogs’ superiority! Research studies have reported a variety of health benefits provided to owners by their dogs; perhaps most pertinent to this newsletter being those related to allergies.

Selfies

Dear Dr. K: Among the many challenges and downsides of our smartphones, can you point to any not-so-obvious upsides to these instruments we glue our eyeballs to?   As it turns out, today’s craze in smartphone selfies may have some medical value that extends beyond vanity. To date, three medical conditions have been diagnosable from selfies: pancreatic cancer, skin cancers and oxygen desaturation.

Q – Tips: Don’t get burned…

If you are going to get cut or burned, do it during daylight hours. Scientists have discovered a marked circadian (body clock) difference in healing from injuries.

Dear Dr. K: Until my husband recently came to see you I didn’t realize there was any other type of allergy tests than the prick tests I received. Can you explain? The skin test your husband received was patch-testing to try to ferret the cause of his skin rash. The test is designed to determine if he is sensitive to any contact allergens.

Sensitive – but timely and critical conversation for families to have

 Death. Unfortunately, in my line of work, it’s part of my daily life. If you’ve had an appointment with my dad anytime in the past year, you know that I recently shifted gears from an Emergency residency to a Critical Care fellowship. Having spent the last several years in the Emergency Department (ED), I’d forgotten what a different beast death is in the Intensive Care Unit (ICU). In the ED, death is swift, often unexpected and sometimes merciful. ICU deaths…

Pepper trees also get a bad rap

Pepper trees also get a bad rap

The Brazilian Pepper tree – also known as the Florida Holly – is an invasive species from South America that has spread throughout Florida and the Southeastern U.S. Many Floridians hate it because it is a common source of contact dermatitis similar in nature to poison ivy. Despite this mischievous aspect of the plant, immunologists have discovered it has incredible antibiotic properties. Amazonian native healers have used the plant for hundreds of years for its medicinal value. Now modern science…
