1 The Impact of Climatic and Environmental Factors for Asthma ER Visits in NYC Cindy Law Mary Lee-Wong, MD

2 What are Allergies? An abnormal sensitivity to an allergen that is inhaled, eaten, or touched Misidentification of a harmless substance as harmful

3 Common Types of Allergies Allergic rhinitis Food Medication Insect stings Latex chemical

4 Allergies and the Immune System B-lymphocytes &T- lymphocytes Lymphocytes identifies a foreign invader Foreign antigens cause production of antibodies 5 types of immunoglobulins

5 Allergy Cascade

6 Places and Symptoms of Reactions The sensitized immune system produces antibodies against allergens which cause the release of histamines into bloodstream

7 What is Asthma? Chronic lung condition with Inflammation of the airways Increased sensitivity of the airways Obstruction of airflow

8 Normal Bronchial Tubes

9

10 Airways

11 Symptoms of Asthma Coughing Wheezing Chest tightness Shortness of breath Faster/ noisy breathing

12 What causes Asthma? Allergens Irritants Others

13 Levels of Asthma Mild intermittent Mild persistent Moderate persistent Severe persistent

14 Spirometry Test Measures how much and how fast air can move into your lungs 60%-79%; mild 40%- 59%; moderate <40%; severe

15 Inhalers

16 Pollen Count Rotorod Sampler 0-14; low 15-89; moderate ; high <1500; very high

17 Pollen Grains

18 Objective Seasonal variables such as increased temperatures, relative humidity, mold counts and pollen counts may contribute to increased ER visits for asthma and other upper respiratory symptoms. Previous studies have reported increased ER visits for asthma due to increased air pollution at different times of the year. Since pollen can cause asthma exacerbation, we investigated whether there is a strong correlation of asthma exacerbation when pollen counts are at their highest.
