Buckwheat anaphylaxis is commonly recognized in Europe and Asia, and there is only one case reported in Taiwan so far. Here, we report a case of biphasic buckwheat anaphylaxis in a 57 year-old male patient who lost consciousness twice in the same day after having buckwheat noodles. The serum test shows that Dermatophagoides pteronyssinus (Dp)immunoglobulin E (IgE) (42.4 kU/L) and buckwheat-specific IgE (81.5 kU/L) are unusually high. Although biphasic buckwheat anaphylaxis is rare, we should still be aware the second episode could be life-threatening and happen within a day after the exposure to the buckwheat antigen...

BACKGROUND: The goals of asthma management aim to control the symptoms and minimize future risk. There is, however, an option to stop controller medication if the patient has been well-controlled for at least 6-12 months. To assess control, both clinical symptom assessment and lung function should be monitored periodically. In practical clinical practice of pediatric patients, lung function is not available at all health centers. OBJECTIVES: to determine lung function with a focus on small airway function and the risk of reversibility among children who have been symptom-controlled...
