“…Since 1974, a total of eight cases of radish allergy have been reported in the literature, including this case (Table 2) [5][6][7][8][9][10][11]. Oral mucositis was observed in three cases, and oral cavity involvement was not mentioned in ve other cases.…”

Background:Oral allergy syndrome (OAS) is a type of food allergy that manifests as hypersensitivity symptoms of the oropharyngeal mucosa on ingestion of specific foods with oral findings resembling herpetic gingivostomatitis. Symptoms can also appear in parts other than the oral cavity. There are a few reports of OAS caused by consuming radishes in the literature.Case presentation:A 31-year-old male presented to our department with stomatitis and pharyngeal pain. The patient did not have a history of allergy, and herpetic gingivostomatitis was suspected. He was admitted to the emergency room of our hospital after complaining of oral and epigastric pain a few days later. On admission, symptoms noted were similar to those when he first visited our department. After detailed history taking, he reported consuming raw Japanese radish frequently, which gave rise to his symptoms. Radish was strongly suspected as the causative allergen. The skin prick test result was positive, confirming the diagnosis of OAS.Conclusions:OAS can be diagnosed easily once the food causing symptoms is identified. However, guiding the diagnosis can be challenging if the patient is unaware of food allergies. Upon encountering widespread erosion in the oral cavity, it is essential to consider OAS as the possible cause.

“…In determining the interval, we revisited the considered weakness of allergenicity. For example, root vegetables rarely cause food allergies, 11 so they were used for 3 days before the next food. In contrast, soy and wheat were considered major food allergens, and so were tested with 2 week intervals.…”

Background Eosinophilic gastrointestinal disorders (EGID) are a group of conditions with increased eosinophilic infiltration in any part of the gastrointestinal tract. Although an allergic reaction to certain foods is considered the main cause of EGID, their detailed pathomechanism has not yet been elucidated, nor have proper management strategies been fully established. Moreover, some patients with intractable EGID are resistant to such therapies as an empirical elimination diet and corticosteroids. Methods We analyzed retrospectively the medical records of four children with intractable eosinophilic gastroenteritis (EGE) managed with elemental diet therapy (EDT) using an amino acid‐based formula. Results All patients displayed resolution of their symptoms after 2 weeks of EDT. Three patients successfully completed food reintroduction and could return to their normal life. No adverse events related to EDT were recorded. Conclusions Elemental diet therapy appears effective and safe for treating pediatric intractable EGE symptoms. Afterwards, the patient’s dietary habits should be considered during carefully monitored food reintroduction. With the relatively small number of published case reports and no randomized trials, more study is needed on EDT for EGE.
