Peppers4, R. Hostoffer5,1. University Heights, OH; 2. Carey, OH; 3. Richmond Heights, OH;4. Concord Township, OH; 5. Highland Heights, OH.Introduction: Seasonal pollen counts affect symptom severityexperienced by susceptible patients. Predicting pollen burden mayenable physicians and patients to better treat their symptoms.Prognostic indicators for pollen season severity are not alwaysreliable. Our investigation focuses on the possible correlationbetween winter weather and the ability to predict outcomes of thetree pollen season in Northeast Ohio.Materials and Methods: Pollen counts were performed in North-east Ohio from 2010-2014. These counts were compared withaverage winter temperatures, precipitation, and snowfall. Fivepollen parameters, (tree, grass, weed, ragweed, and mold), wereevaluated. The weather data was collected from: http://www.cleveland.com/datacentral/index.ssf/2008/09/cleveland_weather_history_ﬁnd.html.Results: Of the ﬁve allergens evaluated, only tree pollen appear tobe affected by winter weather conditions. With increased temper-atures, the number of days with pollen being absent increased, dayswith low pollen counts decreased and days with high pollen countsincreased. Likewise, with a decrease in temperature, absent pollendays decreased, low pollen days increased, and high pollen daysdecreased. No clear conclusion could be drawn from the moderatepollen counts. Tree pollen counts appeared to increase withincreased winter snowfall. There is no apparent correlationbetween winter precipitation and tree pollen counts.Conclusion: Evidence suggests a potential link between winterweather conditions and spring tree pollen counts. A possible cor-relation is demonstrated between average winter temperaturesand tree pollen; a probable correlation exists between averagewinter snowfall and tree pollen. Warmer winter weather patternsmay be predictive of more days with high tree pollen counts duringthe spring season.P052THREE MAXIMUM PEAKS OF THE RAGWEED POLLENSEASON IS NOW AN ESTABLISHED TREND IN UKRAINEV. Rodinkova*1, O. Palamarchuk1, L. Kremenska1, O. Bilous1,L. DuBuske2, 1. Vinnitsa, Ukraine; 2. Gardner, MA.Background: Ragweed pollen has biological rhythms inﬂuenced byglobal temperature increases.Method: Pollen counts from March 1 until October 31 in 1999 to2000 were obtained by gravimetric sampling and from 2009 to2016 used volumetric methods employing a Burkard trap placed ata height of 25 meters above the ground at Vinnitsa MedicalUniversity.Results: Two main periods of pollen count increase were seen forAmbrosia initially. Ragweed a short-day plant pollinationdepending on photoperiodism, had maximum pollination at theend of August in 1999 and 2000. The second pollen countincrease seen in September is signiﬁcantly impacted by temper-ature increases. This two-maximum periodicity changed in recentyears with addition of another period of high ragweed pollenseen in early or mid-August starting in 2010. Increased ragweedpollen occurs with increased daily temperature. Three maximumpeaks of the pollen seasons were seen in 2010, 2013-2015.Intensity of ragweed pollination is regulated by humidity withlow precipitation in June, providing a seasonal peak in Septemberaugmented by high daily air temperature and rains in August orearly September. With higher September temperature, a laterDownloaded for Anonymous User (n/a) at Universidad Autonoma de NuFor personal use only. No other uses without permission.peak occurs. The latest Ragweed peak pollen count occurred onSeptember 18, 2012 and on September 11, 2015, both beingseasonal peaks. The peak occurred no later than September 6 in1999 and 2000.Conclusion: Ragweed pollen season peaks are impacted byglobal temperature increase which induces ragweed to producemore pollen in the beginning of August and increases pollinationin September when weather conditions also include highhumidity.P053PREVALENCE OF FOOD ALLERGEN SENSITIZATION INPATIENTS WITH MUGWORT ALLERGYM. Ochoa Montemayor*, S. Gonzalez-Diaz, A. Arias-Cruz,A. Macias-Weinmann, D. Sánchez-Guerra, Monterrey, NL, Mexico.Introduction: Mugwort allergy has been associated with oralallergy syndrome with celeriac, mango, apple, peach, melon, pep-per, carrot, broccoli, cauliﬂower, cabbage, mustard, garlic andonion.Methods: Retrospective, observational, descriptive study. Weincluded 205 patients with food and aeroallergen skin prick tests.SPT with positive results to Mugwort were comparedwith food SPTresults.Results: Positive SPT to Mugwort 21/205 patients (10.2%). Fromthose, 15/21 (80.9%) with positive food SPT. Positive results inorder: Bean 6/21 (28.5%), shrimp (23.8%), watermelon, canta-loupe, pea, soybean (19%), turkey meat, casein, sardine, peach,orange, grape, cacao, almond, beet, pumpkin, lettuce (14.2%), eggwhite, egg yolk, tuna, sea bass strawberry, peanut, bell pepper,cauliﬂower, green bean, rice, corn, wheat, pepper (9.5%), beef,apple, papaya, lime, coffee, onion, tomato, zucchini, barley,mustard (4.7%). We found monosensitization 4/15 (%), 2-3 sen-sitizations 4/15 (%), more than 4 sensitizations 7/15 (%). Out ofthe reported sensitization SPT were positive to melon, peach, bellpepper, cauliﬂower, apple and onion.Conclusion: Sensitization to reported cross-reactive allergens wasnot as prevalent, coming behind two food allergens not associatedwith Mugwort allergy. Previous reports of our center have showedsensitization to milk, egg, and ﬁsh, as the main allergens. Findingoral allergy syndrome in patients withMugwort allergywas not theobjective of this study, however it opens up new opportunities forfurther research.P054DIFFERENCES IN SENSITIZATION TO POLLEN IN ADULTSAND CHILDREN WITH RESPIRATORY ALLERGY INNORTHEASTERN MEXICOC. Macouzet-Sánchez*1, S. Gonzalez-Diaz2, A. Arias-Cruz2,J. Ibarra-Chávez2, 1. Apodaca, NL, Mexico; 2. Monterrey, NL, Mexico.Introduction: In northeastern Mexico, sensitization to regionalgrass, weed and tree pollen allergens causes and triggers respira-tory allergy including allergic rhinitis and asthma. The aim of thisstudy is to assess the difference in sensitization to pollen allergensamong children and adults with respiratory allergy tested in anallergy center.Methods: A retrospective study was conducted, obtaining datafrom the records of skin tests (ST) performed in patients of aregional allergy center in Monterrey, Mexico, from January 2010 toDecember 2015, including 20 regional pollen allergens.Results: 5825 records were reviewed (2900 patients <18 yearsold and 2925 adults with allergic rhinitis, asthma or both). Themost frequent positive ST were for Fraxinus americana (21.4%),Cynodon dactylon (20.6%) and Atriplex canescens (17.7%). Theevo Leon from ClinicalKey.com by Elsevier on October 11, 2018.
