Foundations for Future Health Care Providers: Immunology 101

As much as we try to improve our health with exercise, a balanced diet, and good hygiene, our well being is largely determined by the immune system.

Learn about this complex coordination of organs from immunology expert, Katherine Gundling, MD, Associate Clinical Professor of Allergy and Immunology at UCSF, and Practice Chief of the Allergy/Immunology clinic at Moffitt Hospital.

She explains that our immune system is responsible for combating external threats, like viruses or physical injuries, and internal threats, such as cancer. But, before our immune system can protect us from these threats, it must regulate functions within the body to determine whether such entrants and occurrences are friend or foe.

Sometimes our immune systems make mistakes and react negatively to things that aren’t really so harmful, such as cat dander, causing allergies. But more severe dysfunctions of the immune system, like a primary immune disorder, can have more devastating effects. Watch “Immunology 101: The Basics and Introduction to our Patient” to meet Elizabeth, a patient with a primary immune disorder, and see how this disorder can teach us about the way a healthy immune system functions.

Fighting food Allergies in Children

Every three minutes some one goes to the emergency room because of an allergy-related event.

When you have an allergic reaction to something you eat, your body recognizes a protein in the food and reacts against it. There are many different responses that can happen-rashes, hives, diarrhea-but, the most dangerous occurrence is when there is potential for anaphylaxis, which can cause death.

In this episode of Health Matters, Dr. David Granet talks with UC San Diego’s Dr. Stephanie Leonard who is the director of the Food Allergy Center at Rady Children’s Hospital here in San Diego.

More than 3 million people under the age of 18 have been diagnosed with food allergies, but Dr. Leonard says that number is on the rise. In a ten year period, she says, there has been an 18% increase in the diagnosis of food allergies in children.

Watch “Children’s Food Allergies- Health Matters” to hear the various theories behind why that number is increasing.
