Ask the doctors

Q. I have fairly thick hair in the summer, but it seems to thin out in late fall. Is there anything I can do now to prevent losing hair in a few months?

A. Sadly, no. What you've experienced is common to all of us. On average, about 90% of the hairs on our heads are in the growing phase and about 10% are in the resting phase. After a few months in the resting phase, the hairs are shed. It's normal to shed up to 100 hairs a day.

On call

If you do end up with a tick “on board” it is important to remove it correctly and know when to call your doctor.

An insect known as the kissing bug has the ability to pass along Chagas’ disease to unsuspecting people. While it affects more people in Latin America than in this country, this parasitic disease can still be a problem in the southwestern United States. Most cases of Chagas’ disease pass without much incidence, but it can cause lasting problems. The rates of Chagas’ disease could go up with climate change, and more research is definitely needed. Charles Darwin may be one of the first “researchers” on the subject, but he’s not to be the last.

The CDC and the AAP update their vaccine recommendations every year, and here are the latest changes.
