Abstract

Patients with "allergy" to iodine and shellfish often do not obtain necessary radiologic procedures due to anxiety about potential radiocontrast media reactions. This study assesses the impact of an educational intervention to dispel these myths. The authors surveyed 252 internal medicine, emergency medicine, pediatrics, radiology, obstetrics/gynecology, and surgery health professionals before and after an educational intervention. Pre- and posttest responses were analyzed to assess the impact of the intervention on beliefs about radiocontrast media reactions and their perceived relationship to shellfish allergy and iodine "allergy." The mean pre- and posttest correct response scores were 41% and 91%, respectively. The intervention had a greater impact on respondents' knowledge about iodine allergy than shellfish allergy, most likely due to the difference in baseline knowledge (P < 0.005). Emergency medicine garnered the highest pretest correct response score (54%). Internal medicine earned the lowest pretest score (30%). There was a significant difference between the highest and lowest scoring specialties on the pretest (P = 0.037). There was no statistically significant correlation with training levels. There was a considerab...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
