For most people, the home is a refuge and an oasis, a place to feel safe. But few ever wonder whether their homes and the everyday household items they use to clean and maintain them could be detrimental to their health.
Joining Dr. Brian McDonough to discuss the unsettling health risks behind common household items, and what consumers should keep an eye on, is Andre LaCroix, Vice President of Easy Breathe, Inc.
Over the past decade, Food Protein Enterocolitis, or FPIES, has emerged as the most actively studied non–IgE-mediated gastrointestinal food allergy because of its acute onset, severity of symptoms, and distinctive clinical features. Yet as a rare allergic disorder of infancy and young childhood, it is often misinterpreted and misdiagnosed in clinical practice, leading to difficult treatment paths for patients and their families. Joining Dr. Renee Matthews to present a case history from the vantage point of a patient's mother, including challenges faced in reaching the correct diagnosis and starting effective treatment regimens, is Jennifer Kandt.
Host: Brian P. McDonough, MD, FAAFP
As an unforgivingly cold, frigid winter in America has led to the explosive release of tree pollens over a short period this spring, seasonal allergies have returned with a vengeance. Says, Dr Mitchell Gaynor, clinical assistant professor of medicine at Weill Cornell Medical College in New York City, this could make for one of the worst allergy seasons of all time. How can primary care providers ready themselves on the frontlines of this mass allergy assault?

The incidence of asthma has doubled in the past two decades, though the cause of this rise is difficult to pinpoint. While the hygiene hypothesis has, for years, served as one possible explanation, newer studies show a possible link between asthma and vitamin levels or exposure to certain chemicals or medications. How might this knowledge help us prevent the development of asthma, and what research still needs to be performed to determine the key factors here, and put an end to the increasing incidence of asthma? Dr. Harold Nelson, professor of medicine at the University of Colorado School of Medicine and National Jewish Health hospital in Denver, lays out the evidence for these potential risk factors, from the child's date of birth, to acetaminophen use, to vitamin D levels, to exposure to cleaning sprays and other household chemicals. Dr. Jennifer Shu hosts.

Host: Jennifer Shu, MD, FAAP
Long-acting, single-agent beta agonists should be used in tandem with a corticosteroid for the treatment of asthma. Despite a black box warning from the Food and Drug Administration (FDA) to this effect, evidence suggests nearly half of our patients do not take these medications together, which appears to result in more severe asthma attacks and an increased mortality risk. In theory, longer-acting beta agonists (LABAs) should help with compliance, but if these single-agent drugs aren't taken as recommended, is there a role for them in the treatment of asthma? Dr. Jesse Joad, professor of pediatrics at the University of California, Davis School of Medicine and a former member of the FDA's Pulmonary and Allergy Drug Advisory Committee, talks with host Dr. Jennifer Shu about the pharmacologic and logistical differences between LABAs taken as monotherapy and LABAs taken in combination with a steroid. Dr. Joad …

Wheat, eggs, milk, peanuts and other nuts, soybeans and seafood: all of these can be an integral part of a balanced, healthy diet for growing children. Instead, many are off-limits for an increasing number of children diagnosed with food allergies. Though the rise in food allergies is certainly worrisome, we're learning that some food allergies may actually be misdiagnosed. Host Dr. Jennifer Shu welcomes Dr. David Fleischer, assistant professor of pediatrics at the University of Colorado School of Medicine and National Jewish Health in Denver, for a conversation about how we can improve our capacity to accurately assess food allergies, and help many of our young patients tolerate, or even enjoy, a wider range of food. Starting with a clinical history, what kind of workup should be done before patients are referred to an allergist? How should allergen-specific antibody blood tests be incorporated into this process?
Guest: Bob Baltera
Host: Bruce Japsen
Asthma remains a difficult disease to treat and control, with a large portion of the patient population not receiving adequate treatment options.
